public abstract class AffectedTestTask
extends org.gradle.api.DefaultTask

Gradle task that detects affected tests and executes them.

Execution flow:

1. Detects git changes against the configured base ref
2. Maps changed files to production/test classes
3. Discovers which test classes are affected
4. Groups FQNs by owning subproject and runs :<module>:test --tests <fqn> once per module so that --tests filters don't cross module boundaries

Not compatible with Configuration Cache: reads live git state and scans the file system at execution time. The task is also deliberately marked as never up-to-date so git changes always trigger a re-run.

public AffectedTestTask()

Method Details

getBaseRef

@Input
public abstract org.gradle.api.provider.Property<String> getBaseRef()

Git base ref to diff against. Default: "origin/master". Override via -PaffectedTestsBaseRef=....

Returns:

the base ref property

getIncludeUncommitted

@Input
public abstract org.gradle.api.provider.Property<Boolean> getIncludeUncommitted()

Whether to include uncommitted (unstaged) changes in the diff. Default: true.

Returns:

the include uncommitted property

getIncludeStaged

@Input
public abstract org.gradle.api.provider.Property<Boolean> getIncludeStaged()

Whether to include staged (added to index) changes in the diff. Default: true.

Returns:

the include staged property

getRunAllIfNoMatches

@Input
public abstract org.gradle.api.provider.Property<Boolean> getRunAllIfNoMatches()

Whether to run the full test suite when no affected tests are found. Default: false (skip tests when nothing is affected).

Returns:

the run-all-if-no-matches property

getRunAllOnNonJavaChange

@Input
public abstract org.gradle.api.provider.Property<Boolean> getRunAllOnNonJavaChange()

Whether to force a full test run when the change set contains any file that cannot be resolved to a Java class under the configured source/test directories (e.g. application.yml, build.gradle, a Liquibase changelog). Excluded paths are honoured and do not trigger the escalation. Default: true — "run more, never run less".

Returns:

the run-all-on-non-java-change property

getStrategies

@Input
public abstract org.gradle.api.provider.ListProperty<String> getStrategies()

Discovery strategies to use for finding affected tests. Valid values: "naming", "usage", "impl", "transitive". Default: all four.

Returns:

the strategies list property

getTransitiveDepth

@Input
public abstract org.gradle.api.provider.Property<Integer> getTransitiveDepth()

How many levels of transitive dependencies to follow when the transitive strategy is enabled. Range: 0 (disabled) to 5. Default: 2.

Returns:

the transitive depth property

getTestSuffixes

@Input
public abstract org.gradle.api.provider.ListProperty<String> getTestSuffixes()

Suffixes used by the naming strategy to find test classes. Default: ["Test", "IT", "ITTest", "IntegrationTest"].

Returns:

the test suffixes list property

getSourceDirs

@Input
public abstract org.gradle.api.provider.ListProperty<String> getSourceDirs()

Production source directories relative to each module root. Default: ["src/main/java"].

Returns:

the source dirs list property

getTestDirs

@Input

Whether to include tests for implementations of changed interfaces/base classes. Default: true.

Returns:

the include implementation tests property

getImplementationNaming

@Input
public abstract org.gradle.api.provider.ListProperty<String> getImplementationNaming()

Suffixes for finding implementation classes (e.g. "Impl" matches FooServiceImpl for a changed FooService). Default: ["Impl"].
