Testing
Unit tests
JUnit tests are the simple and fast tests that use mocks to check simple, single functionality. You should write JUnit to check every function that you use in your code. JUnit must be fast, it should be matters of seconds to run that test.
...
It is a file which contains steps definitions. It contains source code which should be done within a test step. Parameters defined in feature files are passed to step definitions with regular expressions. To make them work correctly, you should configure methods for each step defined in Feature file. Each step is preceded by an annotation connected to step keywords defined in feature file (e.g. @Then, @When etc.).
Example step definition:
| Code Block |
|---|
@Given("I have a cucumber step")
public void i_have_a_cucumber_step() throws Throwable {
System.out.println("Step definition exact match"); |
...
To run our test all we have to do is just run our test
If everything was configured correct, we should got message about completed tests.
After completed tests Cucumber automatically generate report file, where you can check what was tested, or if something went wrong where was the problem. Report file is generated as file (...)/<moduleName>/target/cucumber/index.html.
Example test
Feature file

Feature: testData
Scenario:
Given Configured properties
When I fetch project history data
And I get Revisions from file JIoEndpoint.java
Then Author should match "markt"
And Comment should contain "Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=53063"
And New file content should contain "setMaxConnections(getMaxThreadsExecutor(true));"
And New file content should not contain "setMaxConnections(getMaxThreads());"
And Old file content should contain "setMaxConnections(getMaxThreads());"
And Old file content should not contain "setMaxConnections(getMaxThreadsExecutor(true));"
And revision number should be equal to "1336884"
And File change type should be defined with "CHANGED_CONTENT" |
