Location of the Golden Master files and test reports

When calling Recheck#capTest(), recheck either creates a diff in form of a test report (see below) using the existing Golden Master or—if it is the first time a test is being executed—it creates the Golden Master itself and fails the test.

Note that it is important to fail the test if no Golden Master can be found. As mentioned before, this always happens the first time a test gets executed, but it can also happen for a variety of other reasons. For instance, when someone forgets to add the Golden Master to the version control system or if a test or a folder is renamed. If this is the case, then you definitely want the test to fail.

If you want to configure where recheck puts the Golden Master files, you can do so via a piece of code. The reason for this is that we usually don't want a fixed name, but a name per test or per suite. To determine where to put the Golden Master, RecheckImpl uses the given FileNamerStrategy, which in turn yields a FileNamer. The default FileNamerStrategy is the MavenConformFileNamerStrategy. It creates Golden Masters under src/test/resources/retest/recheck/ and test reports inside target/test-classes/retest/recheck/.

Alternatively, you can use the GradleConformFileNamerStrategy (or implement your own FileNamerStrategy) and pass is to RecheckImpl via RecheckOptions:

RecheckOptions options = RecheckOptions.builder()
        .fileNamerStrategy( new GradleConformFileNamerStrategy() )
Recheck re = new RecheckImpl( options );

When it comes to test reports, recheck uses the very same FileNamerStrategy to create reports for each test suite, which usually denotes a test class. For this we use the following mapping:

recheck class Test entity
SuiteReplayResult Test class
TestReplayResult Test method
ActionReplayResult Check

Suppose the following recheck-web test:

class MyRecheckWebTest {

    WebDriver driver;
    Recheck re;

    void setUp() {
        driver = new ChromeDriver();
        re = new RecheckImpl();

    void someTest() throws Exception {
        driver.get( "https://example.com/" );

        re.check( driver, "1st-page" );

        driver.findElement( By.id( "someLink" ) ).click();
        re.check( driver, "2nd-page" );


    void tearDown() {


In case there are differences, this would result in a test report MyRecheckWebTest.report (a test report with a single SuiteReplayResult) that contains a TestReplayResult for someTest() and two ActionReplayResults for both checks ("1st-page" and "2nd-page").

So for every test class, you get a separate test report that is represented as a tree of test methods and their corresponding checks. Additionally, we provide an aggregated tests.report that includes all test classes.
