You can configure Gauge as per your requirements by using key value pairs in the gauge.properties and default.properties files.

The global key value pairs, in the gauge.properties file, allow you to configure Gauge across all Gauge projects. For example, you can change the timeout value of Gauge when Gauge connects to plugins by changing the value of the plugin_connection_timeout key. This value applies to all Gauge projects.

The local key value pairs, in the default.properties file, allow you to configure Gauge for a particular Gauge project. For example, you can have separate Gauge reports or a single, new, time-stamped directory created (overwrite previous report) every time Gauge runs a specification by using the overwrite_reports key.

Note

You can open the .properties file by using any text editor.

Global configuration of Gauge (gauge.properties)

gauge.properties is a .properties file that contains all Gauge specific configurations. You can use or change the key value pairs present in this file to configure Gauge across all Gauge projects. This file is located at ~/.gauge/config in macOS and Linux systems and at %APPDATA%\Gauge\config in Windows systems.

You can also use the gauge config command to change the value of a key in the gauge.properties file.

gauge config [flags] [args]

Example

For example, to change the value of check_updates in gauge.properties, use the command in the following way:

gauge config check_updates false

This changes the value of the key, check_updates, to false.

The list of key value pairs present in gauge.properties are listed as follows:

# Allow Gauge and its plugin updates to be notified to the user.
check_updates = true

# Set to a URL, which acts as plugin repository for Gauge.
gauge_repository_url = https://downloads.gauge.org/plugin

# Set to a URL, which acts as a template repository for Gauge.
gauge_templates_url = https://downloads.gauge.org/templates

# Timeout in milliseconds for requests from language
# runner when connecting to IDE.
ide_request_timeout = 30000

# Sets the timeout in milliseconds for Gauge while
# connecting to plugins (except language runner plugins).
plugin_connection_timeout = 10000

# Sets the timeout in milliseconds for a plugin to stop
# after a kill message has been sent.
plugin_kill_timeout = 10000

# Sets the timeout in milliseconds for Gauge while
# connecting to the language runner.
runner_connection_timeout = 30000

# Sets the timeout in milliseconds for requests from the
# language runner to Gauge.
# If the size of the Gauge project is too big, Gauge might time out before the
# language runner returns the response message.
runner_request_timeout = 10000

Local configuration of Gauge (default.properties)

default.properties is a .properties file that contains key value pairs. You can use or change the key value pairs present in this file to configure a particular Gauge project. The changed value overrides the default value of a key. This file is located at <project_root>/env/default, where <project_root> is the location at which you have created your Gauge project.

The list of key value pairs present in default.properties are listed as follows:

# The path to the gauge reports directory should be either relative to
# the project directory or an absolute path.
gauge_reports_dir = reports

# Set as false if gauge reports should not be overwritten
# when Gauge runs a specification.
# If set to true, a new, time-stamped directory is
# created every time when Gauge runs a specification.
overwrite_reports = true

# Set to false to disable screenshots on failure in Gauge reports.
screenshot_on_failure = true

# The path to the Gauge logs directory should be either relative to the
# project directory or an absolute path.
logs_directory = logs

# Set to true to use multithreading for parallel execution
enable_multithreading = false

# Specify the level at which in-memory objects should get removed when
# Gauge runs a specification.
# Possible values for this property are 'suite', 'spec' or 'scenario'.
# default: 'scenario'.
# If set to 'spec', the objects are cleared after Gauge runs each specification
# so that new objects are created when Gauge runs the next specification.
gauge_clear_state_level = spec

# The path to the gauge specifications directory.
# Takes a comma separated list of specification files or directories.
gauge_specs_dir = specs

# CsvDelimiter holds delimiter used to parse csv files
# default: `,`
csv_delimiter = ,

# Allows steps to be written in multiline
allow_multiline_step = false

Language plugin configurations

<language>.properties is the .properties file corresponding to the language plugin that you have used while creating a Gauge project. Configuration properties set in these files are available as environment variables when Gauge runs a specification. You can use these properties or change them as per your requirements.

Note

<language>.properties file is automatically created when a Gauge project is created and initialized with a language of your choice.

You can find the language specific .properties file at <project_root>/env/default/<language>.properties, where <project_root> is the location at which you have created the Gauge project. For example, if you have installed Java on your system, then the path of the .properties file is <project_root>/env/default/java.properties.

For more details about running language plugins as an environment, see Environments.

If you have installed Java, then you can make Java specific configuration changes in the java.properties file. The following key value pairs are listed in java.properties:

# Specify an alternate Java home if you want to use a custom version of the Java Development Kit (JDK).
gauge_java_home = PATH_TO_JAVA_HOME

# Use this property if you need to override the build path for the Gauge project.
# IntelliJ Idea and Eclipse out directory are usually auto-detected.
gauge_custom_build_path = PATH_TO_CUSTOM_BUILDPATH

# Specify the directory where additional libraries are kept.
# You can specify multiple directory names separated with a comma `,`
# `libs` directory in the gauge project is added by default.
gauge_additional_libs = libs/*, PATH_TO_NEW_LIBRARY

# Specify the JVM arguments passed to Java while launching.
# Enter multiple values separated by comma (,). For example, Xmx1024m, Xms128m
gauge_jvm_args = <JVM_ARGS>

# Specify the directory containing Java files to be compiled.
# You can specify multiple directory names separated with a comma (,).
gauge_custom_compile_dir =

# Specify the level at which the in-memory objects should be cleared
# Possible values are suite, spec, and scenario. Default value is scenario.
gauge_clear_state_level = scenario

If you have installed JavaScript, then you can make JavaScript specific configuration changes in the js.properties file. The following key value pairs are listed in js.properties:

1
2
3
4
5
6
7
8
# Use this property if you need to override the timeout of a step when Gauge runs the step in a specification.
test_timeout = 10000

# Change this to true to enable browser debugging support
DEBUG = false

# Comma separated list of directories or paths (a path should be relative to project root).
STEP_IMPL_DIR = tests

If you have installed Python, then you can make Python specific configuration changes in the python.properties file. The following key value pair is listed in python.properties:

# Comma separated list of dirs. path should be relative to project root.
STEP_IMPL_DIR = tests

If you have installed Csharp, then you can make Csharp specific configuration changes in the csharp.properties file. The following key value pair is listed in csharp.properties:

1
2
3
4
5
6
7
8
# Holds the location of the created Gauge project
GAUGE_CSHARP_PROJECT_FILE = /Users/nivedhasenthil/Desktop/sample-csharp/SampleCsharp.csproj

# The build configuration when running tests for the Gauge project
GAUGE_CSHARP_PROJECT_CONFIG = Debug

# The build platform when running tests for the Gauge project
GAUGE_CSHARP_PROJECT_PLATFORM = Any CPU

If you have installed Ruby, then you can make Ruby specific configuration changes in the ruby.properties file. Ruby do not have any specific default configuration properties of its own currently.

HTTP_PROXY setting while using Gauge

Gauge connects to the internet for downloading plugins and templates. If you are behind a proxy, you must configure the proxy settings so that Gauge connects to the internet via the proxy server.

Without Authentication

If authentication is not required, set the environment variable HTTP_PROXY to proxy server URL.

export HTTP_PROXY=http://server-ip:port
export HTTP_PROXY=http://server-ip:port
set HTTP_PROXY=http://server-ip:port

With Authentication

If authentication is required, set the environment variable HTTP_PROXY to proxy server URL along with the credentials.

export HTTP_PROXY=http://username:password@server-ip:port
export HTTP_PROXY=http://username:password@server-ip:port
set HTTP_PROXY=http://username:password@server-ip:port

Gauge configuration while using build tools

If you are using Gauge with the build tools such as Maven or Gradle, then you must be aware of specific configuration properties.

  • For configuration information while using Gauge with Maven, see Gauge Maven Plugin repository.
  • For configuration information while using Gauge with Gradle, see Gauge Gradle Plugin repository.

Using environments in a Gauge project

Environment specific variables can be managed by using property files. The property files have a set of key value pairs which are set as environment variables when Gauge runs a specification. Gauge allows you to create groups of property files by defining an environment.

A Gauge project can have multiple environments. default is the default environment. Gauge uses the –env flag to load an environment, when Gauge runs a specification. If –env is not specified, then the default environment is chosen during run time. Multiple environments can be specified along with the –env flag.

Example

The following example shows an env directory structure for a Java project. default.properties and java.properties are the .properties files created when you create a Gauge project with Java as the language runner. You can use or change the key value pairs in these .properties files as per your requirements.

├── env
  └── default
     ├── default.properties
     └── java.properties

Attention

You can either create a new .properties file or use an existing file to add your custom key value pairs.

Create a new environment in a Gauge project

For ease of testing, you can create an environment in addition to the default existing environment in your Gauge project. You can create a new .properties file or add an existing property file to this new environment and customize the configuration properties as per your requirements.

Before you begin

Ensure that you have created and initialized a Gauge project with a language runner of your choice.

About this task:

A Gauge project can have multiple environments.

default is the default environment.

Create a directory in the env folder of your Gauge project. The environment folder is present at <project_root>, where project_root is the location at which you have created your Gauge project.

mkdir <name_of_env>

Example

Create an environment called ci.

mkdir ci

A ci environment is created at <project_root>/env.

If you want to add your own key value pairs, then create a .properties file within the newly created environment.

Note

You can also add or change the key value pairs in an existing .properties file and use this file in your newly created environment. You can add any number of .properties file to your environment.

Example

The following example shows multiple environments in a Gauge project, where env is located at <project_root>. ci, dev, and experimental are newly created environments in addition to the already existing default environment. The default environment is created when you create and initialize a Gauge project. ci and dev have newly created user.properties file, whereas experimental has default.properties and java.properties, which are already existing files.

├── env
   ├── ci
      |── user.properties
   |── default
      ├── default.properties
      └── java.properties
   ├── dev
      |── user.properties
   ├── experimental
      |── default.properties
      └── java.properties

For more information about language plugin configurations, see Language plugin configuration .

Run a Gauge specification with an environment

You can use the -env flag to load an environment when Gauge runs a specification. During run time, the key value pairs that you have used in the .properties file are set as environment variables. If -env is not specified, then the default environment is loaded during run time.

Before you begin

Ensure that you have the Gauge specification that needs to be run.

You must have already created the environment and added the .properties file in this environment.

Use the following command at <project_root> (location at which you have created the Gauge project) to run a Gauge specification with an environment:

You can use the -env flag to load an environment when Gauge runs a specification. During run time, the key value pairs that you have used in the .properties file are set as environment variables. If -env is not specified, then the default environment is loaded during run time.

gauge run --env <name_of_env> specs

<name_of_env> - name of the environment that you choose to load

Example

In the following example, the ci environment is loaded when Gauge runs a specification.

gauge run --env ci specs

Run a Gauge specification with multiple environments

You can load multiple environments by using the -env flag when Gauge runs a specification. This allows ease of testing.

Before you begin

Ensure that you have the Gauge specification that needs to be run.

You must have already created the environments and added the .properties file in these environments.

About this task:

Gauge loads the environment variables as per the rules of precedence. If there are common environment variables in a user-created environment and the default environment, then the default environment does not overwrite those variables which are already loaded from the user-created environment. If the default environment is not specified explicitly as an argument to the --env flag, then Gauge automatically adds default at the end of the arguments list.

For more information about the precedence of environments, see Precedence of environments.

Use the following command at <project_root> (location at which you have created the Gauge project) to run a Gauge specification with multiple environments:

gauge run --env "<name_of_env_1>, <name_of_env_2>, default" specs

<name_of_env_1,2> - names of the environments that you choose to load

Example

In the following example, ci, experimental, and default environments are loaded when Gauge runs a specification.

gauge run --env "ci, experimental, default" specs

As per the rules of precedence, environment variables from ci are set first, followed by experimental, and then default.

Example

In the following example, environment variables from ci are set first, followed by default, and then experimental.

gauge run –env “ ci, default, experimental” specs

Example

In the following example, though default environment is not explicitly specified as an argument to --env, Gauge automatically adds this environment at the end of the list, which is after experimental.

gauge run –env “ ci, experimental” specs

Precedence of environments when running Gauge

If multiple environments are loaded when Gauge runs a specification, then Gauge follows the rules of precedence to load the environment variables as provided by the user and from the default environment. It is recommended that you understand these rules to run your tests effectively.

The rules of precedence to load the environment variables are as follows:

  • Environment variables provided in the user shell of the user’s operating system.
  • Environment variables (from the environments) provided by the user in the --env flag.
  • Environment variables from gauge.properties (global configuration of Gauge; located at <project_root>/env).
  • Environment variables from the default environment.

Note

If the default environment is not present, Gauge internally sets the environment variables which have the same value as mentioned in default.properties.

Gauge workflow with multiple environments

When Gauge is run with multiple environments, the following events occur:

  1. Gauge loads the environment variables set at the operating system’s user shell.

  2. Gauge loads the environment variables from the environments provided by the user in the --env flag.

    Attention

    If the environment mentioned in the --env flag is not found at <project_root>/env, Gauge ends with a non-zero exit code.

  3. Next, Gauge loads the environment variables from gauge.properties (global configuration).

    Important

    Only those variables that are not yet set are loaded.

  4. Lastly, Gauge loads the default environment variables as follows:

    • If the default directory is not present at <project_root>/env, Gauge internally sets the environment variables as mentioned in default.properties (local configuration).
    • If default is located at <project_root>/env, Gauge loads the environment variables from default.properties.

    Important

    Only those variables that are not yet set are loaded.

For more information about global configuration, see Global configuration of Gauge. For more information about local configuration, see Local configuration of Gauge.

Examples of Gauge workflows

Some of the possible Gauge workflows are listed on this page for your understanding.

Workflow : User runs gauge run specs

default environment is located at <project_root>/env/.

  • If default is not present, Gauge internally sets the environment variables with the same values as mentioned in default.properties (local configuration).
  • If default is present, Gauge sets the environment variables as mentioned in the default environment.

For more information about local configuration, see Local configuration of Gauge.

Workflow : User runs gauge run --env java_ci specs

java_ci is the user-created environment at <project_root>/env.

  • If java_ci is not found, Gauge ends with a non-zero exit code.
  • If java_ci is present, Gauge sets the environment variables mentioned in the java_ci environment. Gauge then loads other environment variables from the default environment which are not yet set. If the default environment is not present, Gauge internally sets the environment variables, which is the same as those in default.properties.

Workflow : User runs gauge_reports_dir=newReportsDir gauge run specs

Note

Alternately, user can explicitly set gauge_reports_dir=newReportsDir in the operating system’s user shell and then run gauge run specs.

default environment is located at <project_root>/env/.

Gauge sets all the environment variables from default. If default is not present, Gauge internally sets the environment variables, which is the same as those in default.properities, except for gauge_reports_dir.

The value of gauge_reports_dir continues to be newReportsDir.

Workflow : User runs gauge_reports_dir=newReportsDir gauge run --env=java_ci specs

java_ci is the user-created environment at <project_root>/env.

Note

Alternately, user can explicitly set gauge_reports_dir=newReportsDir in the operating system’s user shell and then run gauge run --env java_ci specs

Gauge sets the environment variables as mentioned in the java_ci environment except for gauge_reports_dir. The value of gauge_reports_dir continues to be newReportsDir.

Workflow : User runs gauge_reports_dir=newReportsDir gauge run --env “java_ci, experimental” specs

java_ci, experimental are the user-created environments at <project_root>/env.

Note

Alternately, user can explicitly set gauge_reports_dir=newReportsDir in the operating system’s user shell and then run gauge run --env "java_ci, experimental" specs

  • If either one of the user-created environment is not found, Gauge ends with a non-zero exit code.
  • If all the user-created environments are present, Gauge sets the environment variables mentioned in the corresponding environments.
  • Gauge then loads the environment variables, which are not yet set, from gauge.properties.
  • If the default environment is not specified explicitly, then Gauge automatically runs default and loads the environment variables which are not yet set. If default is not present, Gauge internally sets the environment variables, which is the same as default.properties.

The value of gauge_reports_dir continues to be newReportsDir.
