MotionToSuppress

object MotionToSuppress extends Formatter with Product

A Formatter that indicates reporters may wish to suppress reporting of an Event. "Suppress" means that the event won't be reported to the user.

An example is that specification-style suites, such as Spec, generate output that reads more like a specification. One aspect of this is that generally only a single event should be reported for each test, so that output can appear like this:

A Stack (when newly created)
- should be empty
- should complain when popped

ScalaTest suites should generate two events per test, a TestStarting event and either a TestSucceeded or a TestFailed event. The Spec trait does report both events, but passes a MotionToSuppress along with the TestStarting event. As a result, The TestStarting events have no effect on the output. Each TestSucceeded or TestFailed event, which is sent with an IndentedText formatter instead of a MotionToSuppress, will generate output, such as "- should be empty".

Reporters may choose to ignore a MotionToSuppress. For example, an XML reporter may want to report everything about every event that is fired during a concurrent run, so that the events can be reordered later by reading the complete, but unordered, information from an XML file. In this case, the XML reporter would actually report events that were fired with a MotionToSuppress, including indicating that the report included a motion to suppress.

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    The default implementations of this method is an equivalence relation:

    • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
    • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
    • It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

    If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same Int (o1.hashCode.equals(o2.hashCode)).

    arg0

    the object to compare against this object for equality.

    returns

    true if the receiver object is equivalent to the argument; false otherwise.

  3. def hashCode(): Int

    Returns a hash code value for the object

    Returns a hash code value for the object.

    The default hashing algorithm is platform dependent.

    Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.
