Class TagFilter

  • @API(status=STABLE,
     since="1.0")
public final class TagFilter
extends java.lang.Object
    Factory methods for creating PostDiscoveryFilters based on included and excluded tags or tag expressions.

    Tag expressions are boolean expressions with the following allowed operators: ! (not), & (and), and | (or). Parentheses can be used to adjust for operator precedence. Please refer to the JUnit 5 User Guide for usage examples.

    Please note that a tag name is a valid tag expression. Thus, wherever a tag expression can be used, a single tag name can also be used.

        public static PostDiscoveryFilter includeTags​(java.lang.String... tagExpressions)
                                       throws org.junit.platform.commons.PreconditionViolationException
        Create an include filter based on the supplied tag expressions.

        Containers and tests will only be executed if their tags match at least one of the supplied included tag expressions.

        Parameters:
        tagExpressions - the included tag expressions; never null or empty
        Throws:
        org.junit.platform.commons.PreconditionViolationException - if the supplied tag expressions array is null or empty, or if any individual tag expression is not syntactically valid

                                       throws org.junit.platform.commons.PreconditionViolationException
        Create an exclude filter based on the supplied tag expressions.

        Containers and tests will only be executed if their tags do not match any of the supplied excluded tag expressions.

        Parameters:
        tagExpressions - the excluded tag expressions; never null or empty
