Cucumber-Kotlin Shouty

Each learning goal is attached to a git-branch

This is the simplest possible build script setup for Cucumber using Kotlin. There is nothing fancy like a webapp or browser testing. All this does is to show you how to install and run Cucumber!

There is a single feature file with one scenario. The scenario has three steps, two of them pending. See if you can make them all pass!

Get the code

Git:

git clone https://github.com/cucumber/cucumber-java-skeleton.git
cd cucumber-java-skeleton

Subversion:

svn checkout https://github.com/cucumber/cucumber-java-skeleton/trunk cucumber-java-skeleton
cd cucumber-java-skeleton

Or simply download a zip file.

Use Gradle

Open a command window and run:

 ./gradlew test --rerun-tasks --info

This runs Cucumber features using Cucumber's JUnit runner. The @RunWith(Cucumber.class) annotation on the RunCucumberTest class tells JUnit to kick off Cucumber.

Overriding options

The Cucumber runtime parses command line options to know what features to run, where the glue code lives, what plugins to use etc. When you use the JUnit runner, these options are generated from the @CucumberOptions annotation on your test.

Sometimes it can be useful to override these options without changing or recompiling the JUnit class. This can be done with the cucumber.options system property. The general form is:

Using Gradle:

gradlew -Dcucumber.features="..." -Dcucumber.glue="..." test

Run a subset of Features or Scenarios

Specify a particular scenario by line

-Dcucumber.features="classpath:skeleton/belly.feature:4"

In case you have many feature files or scenarios to run against, separate them with commas ,

-Dcucumber.features="src/test/resources/skeleton/belly.feature:4, src/test/resources/skeleton/stomach.feature"

You can also specify what to run by tag:

-Dcucumber.filter.tags="--tags @bar"

Running only the scenarios that failed in the previous run

-Dcucumber.features="@target/rerun.txt"

This works as long as you have the rerun formatter enabled.

Specify a different formatter:

For example a JUnit formatter:

-Dcucumber.plugin="junit:target/cucumber-junit-report.xml"
