Basic usage

Activate the extension by specifying its class in your behat.yml:

Command line options

Add the following to your behat command to print a report:

behat --format html --out MYDIRECTORY

Setting the format to html will output the various reports that you configure below (Behat2, Twig, Minimal, etc.)

You also need to specify the output directory for the reports as MYDIRECTORY.

Configuration

Formatter configuration

• output_path - The location where Behat will save the HTML reports. Use %paths.base% to build the full path.

Extension configuration

• renderer - The engine that Behat will use for rendering, thus the types of report format Behat should output (multiple report formats are allowed, separate them by commas). Allowed values are:
  • Behat2 for generating HTML reports like they were generated in Behat 2.
  • Twig A new and more modern format based on Twig.
  • Minimal An ultra minimal HTML output.
• file_name - (Optional) Behat will use a fixed filename and overwrite the same file after each build. By default, Behat will create a new HTML file using a random name ("renderer name"_"date hour").
• print_args - (Optional) If set to true, Behat will add all arguments for each step to the report. (E.g. Tables).
• print_outp - (Optional) If set to true, Behat will add the output of each step to the report. (E.g. Exceptions).
• loop_break - (Optional) If set to true, Behat will add a separating break line after each execution when printing Scenario Outlines.

Screenshot

The facility exists to embed a screenshot into test failures.

Currently png is the only supported image format.

In order to embed a screenshot, you will need to take a screenshot using your favourite webdriver and store it in the following filepath format:

results/html/assets/screenshots/{{feature_name}}/{{scenario_name}}.png

The feature_name and scenario_name variables will need to be the relevant item names without spaces.

Below is an example of FeatureContext methods which will produce an image file in the above format:

Note that the currentScenario variable will need to be at class level and generated in the @BeforeScenario method as Behat does not currently support obtaining the current Scenario in the @AfterStep method, where the screenshot is generated
