Configuration

Global Configuration: codeception.yml

The global configuration file codeception.yml is generated by the codecept bootstrap command. Alphabetical list of options:

actor_suffix

Sets the suffix for “Actor” classes. Default: Tester. If you set it to Ninja and generate a new api test suite, you will get an ApiNinja actor class.

bootstrap

Bootstrap script that will be executed before all suites. A script should be put into tests directory.

coverage

CodeCoverage settings.

extends

Allows you to specify a file (relative to the codeception.yml file) that holds some already pre-defined values. This can be used to always use the same configuration for modules or whatever.

extensions

Allows to enable and configure Codeception extensions, Group Objects, and Custom Commands.

gherkin

Gherkin options.

include

Include additional Codeception configurations for multiple applications setup.

modules

Allows to create shared module configuration for all included suites.

modules:
    config:
        Db:
            dsn: ''
            user: ''
            password: ''
            dump: tests/_data/dump.sql

namespace

Sets the namespace under which all new tests and support classes will be generated. Allows to configure multiple test setups for one runner.

params

Allows to pass external parameters into module configuration.

paths

Directories used by Codeception. Default values:

paths:
    tests  : tests          # where the tests stored
    data   : tests/_data    # directory for fixture data
    support: tests/_support # directory for support code
    output : tests/_output  # directory for output
    envs   : tests/_envs    # directory for environment configuration

reporters

Allows to change default reporters of Codeception

settings

Provide additional options for the test runner. They may dramatically change the way Codeception is executed. For instance, take a note of shuffle option which allows to randomize tests execution order and lint option that toggles parsing a test file (using php -l) before loading it.

Syntax example:

settings:
    colors: true

Possible settings:

• backup_globals: true: Controls whether PHPUnit attempts to backup global variables, see https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.backupGlobals
• be_strict_about_changes_to_global_state: false: PHPUnit can be strict about tests that manipulate global state, see https://phpunit.de/manual/current/en/risky-tests.html#risky-tests.global-state-manipulation
• colors: true: By default this is false on Windows. Use ANSICON to colorize output.
• convert_deprecations_to_exceptions: false Converts E_DEPRECATED and E_USER_DEPRECATED events to exceptions. Introduced in Codeception 4.2.0
• disallow_test_output: false: PHPUnit can be strict about output during tests, see https://phpunit.de/manual/current/en/risky-tests.html#risky-tests.output-during-test-execution
• editor_url: 'atom://core/open/file?filename=%%file%%&line=%%line%%': In the console output, the test runner will replace all references to files with “clickable” URL’s, allowing you to open the file directly in your IDE. Depending on your operating system, you may have to set up an appropriate uri handler. Syntax for some common editors (same as in PHPStan):
  • PhpStorm: 'phpstorm://open?file=%%file%%&line=%%line%%'
  • Visual Studio Code: 'vscode://file/%%file%%:%%line%%'
  • Atom: 'atom://core/open/file?filename=%%file%%&line=%%line%%'
• error_level: E_ALL & ~E_STRICT & ~E_DEPRECATED: Set the error_reporting level. You can specify either a predefined constant or an integer value, see https://www.php.net/manual/en/function.error-reporting.php and https://www.php.net/manual/en/errorfunc.constants.php
• memory_limit: 1024M: Tests (especially functional) can take a lot of memory. We set a high limit for them by default.
• lint: true: Enable/disable syntax of test files before loading. For PHP < 7 exec('php -l') is used. Disable if you need to speed up tests execution.
• log_incomplete_skipped: false: Log the incomplete and skipped tests into junit report ,see https://phpunit.de/manual/current/en/appendixes.configuration.html Section logging > junit
• report_useless_tests: false: PHPUnit can be strict about tests that do not test anything, see https://phpunit.de/manual/current/en/risky-tests.html#risky-tests.useless-tests
• shuffle: true: Randomize test order
• strict_xml: false: Generate XML JUnit report using strict schema. Avoid putting additional report fields like steps or scenario names to it. Required for XML reports on Jenkins CI

Suite Configuration: unit.suite.yml, functional.suite.yml etc.

Each suite has its own configuration inside the directory set by paths: tests: in codeception.yml. Alphabetical list of options:

actor

Name of the “Actor” class of the current suite.

bootstrap

Bootstrap script that will be executed before current suite. A script should be put into suite directory.

coverage

Per suite CodeCoverage settings.

env

Override any configuration per environment.

error_level

error level for runner in the current suite. Can be specified for unit, integration, functional tests. Passes value to error_reporting function.

extends

Allows you to specify a file (relative to *.suite.yml) that holds some already pre-defined values. This can be used to always use the same configuration for modules or whatever.

gherkin

Per suite Gherkin settings.

groups

groups with the list of tests of for corresponding group.

formats

formats with the list of extra test format classes.

modules

List of enabled modules with their configuration.

modules:
    enabled:
        - PhpBrowser: # built-in modules are listed by their names
            url: http://localhost # module configuration
        - Db # Module without configuration (or inherited from `codeception.yml`)
        - \Helper\Acceptance # helper names are listed by their class names, starting with `\`

    # Additional modules configuration; can be used for modules which are not currently enabled
    config:
        WebDriver:
            browser: firefox

    disabled:
        - WebDriver # modules disabled for this suite

namespace

Default namespace of actor, support classes and tests.

suite_namespace

Default namespace for new tests of this suite (ignores namespace option)

Configuration Templates: *.dist.yml

To provide the same configuration template for your development team, you can create a codeception.dist.yml config file, which will be loaded before codeception.yml. The dist config provides shared options, while local codeception.yml files override them on a per-installation basis. Therefore, codeception.yml should be ignored by your VCS system.

Config templates can also be used for suite configuration, by creating a suitename.suite.dist.yml file.

Configuration loading order:

1. codeception.dist.yml
2. codeception.yml
3. acceptance.suite.dist.yml
4. acceptance.suite.yml
5. environment config
