- ## Method Details

  - ### getEvents

    @Internal Set<TestLogEvent> getEvents()
    Returns the events to be logged.
    Returns:
      the events to be logged

  - ### setEvents

    void setEvents(Set<TestLogEvent> events)
    Sets the events to be logged.
    Parameters:
      `events` - the events to be logged
    Since:
      4.0

  - ### setEvents

    void setEvents(Iterable<?> events)
    Sets the events to be logged.
    Parameters:
      `events` - the events to be logged

  - ### events

    void events(Object... events)
    Sets the events to be logged. Events can be passed as enum values (e.g. `TestLogEvent.FAILED`) or Strings (e.g. "failed").
    Parameters:
      `events` - the events to be logged

  - ### getMinGranularity

    @Internal int getMinGranularity()
    Returns the minimum granularity of the events to be logged. Typically, 0 corresponds to events from the Gradle-generated test suite for the whole test run, 1 corresponds to the Gradle-generated test suite for a particular test JVM, 2 corresponds to a test class, and 3 corresponds to a test method. These values may extend higher if user-defined suites or parameterized test methods are executed. Events from levels lower than the specified granularity will be ignored.

    The default granularity is -1, which specifies that test events from only the most granular level should be logged. In other words, if a test method is not parameterized, only events from the test method will be logged and events from the test class and lower will be ignored. On the other hand, if a test method is parameterized, then events from the iterations of that test method will be logged and events from the test method and lower will be ignored.

    Returns:
      the minimum granularity of the events to be logged

  - ### setMinGranularity

    void setMinGranularity(int granularity)
    Sets the minimum granularity of the events to be logged. Typically, 0 corresponds to events from the Gradle-generated test suite for the whole test run, 1 corresponds to the Gradle-generated test suite for a particular test JVM, 2 corresponds to a test class, and 3 corresponds to a test method. These values may extend higher if user-defined suites or parameterized test methods are executed. Events from levels lower than the specified granularity will be ignored.

    The default granularity is -1, which specifies that test events from only the most granular level should be logged. In other words, if a test method is not parameterized, only events from the test method will be logged and events from the test class and lower will be ignored. On the other hand, if a test method is parameterized, then events from the iterations of that test method will be logged and events from the test method and lower will be ignored.

    Parameters:
      `granularity` - the minimum granularity of the events to be logged

  - ### getMaxGranularity

    @Internal int getMaxGranularity()
    Returns the maximum granularity of the events to be logged. Typically, 0 corresponds to the Gradle-generated test suite for the whole test run, 1 corresponds to the Gradle-generated test suite for a particular test JVM, 2 corresponds to a test class, and 3 corresponds to a test method. These values may extend higher if user-defined suites or parameterized test methods are executed. Events from levels higher than the specified granularity will be ignored.

    The default granularity is -1, which specifies that test events from only the most granular level should be logged. Setting this value to something lower will cause events from a higher level to be ignored. For example, setting the value to 3 will cause only events from the test method level to be logged and any events from iterations of a parameterized test method will be ignored.

    Returns:
      the maximum granularity of the events to be logged

  - ### setMaxGranularity

    void setMaxGranularity(int granularity)
    Returns the maximum granularity of the events to be logged. Typically, 0 corresponds to the Gradle-generated test suite for the whole test run, 1 corresponds to the Gradle-generated test suite for a particular test JVM, 2 corresponds to a test class, and 3 corresponds to a test method. These values may extend higher if user-defined suites or parameterized test methods are executed. Events from levels higher than the specified granularity will be ignored.

    The default granularity is -1, which specifies that test events from only the most granular level should be logged. Setting this value to something lower will cause events from a higher level to be ignored. For example, setting the value to 3 will cause only events from the test method level to be logged and any events from iterations of a parameterized test method will be ignored.

    Note that since the default value of `getMinGranularity()` is -1 (the highest level of granularity) it only makes sense to configure the maximum granularity while also setting the minimum granularity to a value greater than -1.

    Parameters:
      `granularity` - the maximum granularity of the events to be logged

  - ### getDisplayGranularity

    @Internal int getDisplayGranularity()
    Returns the display granularity of the events to be logged. For example, if set to 0, a method-level event will be displayed as "Test Run > Test Worker x > org.SomeClass > org.someMethod". If set to 2, the same event will be displayed as "org.someClass > org.someMethod".

    -1 denotes the highest granularity and corresponds to an atomic test.

    Returns:
      the display granularity of the events to be logged

  - ### setDisplayGranularity

    void setDisplayGranularity(int granularity)
    Sets the display granularity of the events to be logged. For example, if set to 0, a method-level event will be displayed as "Test Run > Test Worker x > org.SomeClass > org.someMethod". If set to 2, the same event will be displayed as "org.someClass > org.someMethod".

    -1 denotes the highest granularity and corresponds to an atomic test.

    Parameters:
      `granularity` - the display granularity of the events to be logged
