After tests have been generated, Cover validates newly created tests by invoking the test phase of your build tool (
Gradle). Cover will then remove any created tests that fail compilation or execution.
Existing unit tests must both compile and pass (
gradle test) before
dcover createis invoked.
--skip-test-validationif this is not the case.
If unvalidated JUnit 5 tests (those which fail to compile or run successfully) are generated by
dcover create, please confirm that running
mvn testactually executes your unit tests. JUnit 5 requires at minimum Maven Surefire v2.22.0 to work, and if an older version is present
mvn testwill pass without executing any tests. You can specify the Surefire Plugin version in your POM using:
<build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.22.2</version> </plugin> </plugins> </build>

Test validation is bypassed if a build tool (
Gradle) is not detected from your environment.
In that case it is possible that some created tests may fail compilation or execution.
Test Validation and user-specified system properties
--define option allows the user to pass additional system properties to
dcover for test creation and execution.
Any created tests may depend upon these user-specified system properties and may not execute successfully without them.
During test validation
dcover will forward user-specified system properties to your build tool, be that
Maven is able to utilize these forwarded properties when executing tests for test validation. No configuration is required.
Gradle does not forward system properties to executed tests and will require further configuration to do so. In such a case test validation is likely to fail out-of-the-box without changes to your
In any case, for
Gradle you will need to configure test execution in your build script to supply these same user-specified system properties when executing those tests outside
