Filter

class Filter extends (Set[String], Map[String, Set[String]]) ⇒ List[(String, Boolean)]

Filter whose apply method determines which of the passed tests to run and ignore based on tags to include and exclude passed as as class parameters.

This class handles the org.scalatest.Ignore tag specially, in that its apply method indicates which tests should be ignored based on whether they are tagged with org.scalatest.Ignore. If "org.scalatest.Ignore" is not passed in the tagsToExclude set, it will be implicitly added. However, if the tagsToInclude option is defined, and the contained set does not include "org.scalatest.Ignore", then only those tests that are both tagged with org.scalatest.Ignore and at least one of the tags in the tagsToInclude set will be included in the result of apply and marked as ignored (so long as the test is not also marked with a tag other than org.scalatest.Ignore that is a member of the tagsToExclude set. For example, if SlowAsMolasses is a member of the tagsToInclude set and a test is tagged with both org.scalatest.Ignore and SlowAsMolasses, and SlowAsMolasses appears in the tagsToExclude set, the SlowAsMolasses tag will "overpower" the org.scalatest.Ignore tag, and the test will be filtered out entirely rather than being ignored.

  1. def apply(testName: String, tags: Map[String, Set[String]]): (Boolean, Boolean)

    Filter one test name based on its tags

    Filter one test name based on its tags.

    The returned tuple contains a Boolean that indicates whether the test should be filtered, and if not, a Boolean that indicates whether the test should be ignored. A test will be marked as ignored if org.scalatest.Ignore is in its tags set, and either tagsToInclude is None, or tagsToInclude's value (a set) contains the passed test name, unless another tag for that test besides org.scalatest.Ignore is also included in tagsToExclude. For example, if a test is tagged with both org.scalatest.Ignore and SlowAsMolasses, and SlowAsMolasses appears in the tagsToExclude set, the SlowAsMolasses tag will "overpower" the org.scalatest.Ignore tag, and this method will return (true, false).

    val (filterTest, ignoreTest) = filter(testName, tags)
    if (!filterTest)
      if (ignoreTest)
        // ignore the test
      else
        // execute the test
    

    testName

    the test name to be filtered

    tags

    a map from test name to tags, containing only test names that have at least one tag

    Go to: companion
  2. def apply(testNames: Set[String], tags: Map[String, Set[String]]): List[(String, Boolean)]

    Filter test names based on their tags

    Filter test names based on their tags.

    Each tuple in the returned list contains a String test name and a Boolean that indicates whether the test should be ignored. A test will be marked as ignored if org.scalatest.Ignore is in its tags set, and either tagsToInclude is None, or tagsToInclude's value (a set) contains the test's name, unless another tag for that test besides org.scalatest.Ignore is also included in tagsToExclude. For example, if a test is tagged with both org.scalatest.Ignore and SlowAsMolasses, and SlowAsMolasses appears in the tagsToExclude set, the SlowAsMolasses tag will "overpower" the org.scalatest.Ignore tag, and this method will return a list that does not include the test name.

    for ((testName, ignoreTest) <- filter(testNames, tags))
      if (ignoreTest)
        // ignore the test
      else
        // execute the test
    

    testNames

    test names to be filtered

    tags

    a map from test name to tags, containing only test names included in the testNames set, and only test names that have at least one tag

  5. def equals(arg0: Any): Boolean

    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.

  6. 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.

  7. def runnableTestCount(testNames: Set[String], tags: Map[String, Set[String]]): Int

    Returns the number of tests that should be run after the passed testNames and tags have been filtered with the tagsToInclude and tagsToExclude class parameters

    Returns the number of tests that should be run after the passed testNames and tags have been filtered with the tagsToInclude and tagsToExclude class parameters.

    The result of this method may be smaller than the number of elements in the list returned by apply, because the count returned by this method does not include ignored tests, and the list returned by apply does include ignored tests.

    testNames

    test names to be filtered

    tags

    a map from test name to tags, containing only test names included in the testNames set, and only test names that have at least one tag

    Go to: companion
  8. val tagsToExclude: Set[String]

  9. val tagsToInclude: Option[Set[String]]

  10. def toString(): String

    Returns a string representation of the object

    Returns a string representation of the object.

    The default representation is platform dependent.
