public AndConstraint<TAssertions> Contain( string expected, OccurrenceConstraint occurrenceConstraint, string because, params object[] becauseArgs )
Parameters
- expected
- The (fragment of a) string that the current string should contain.
- occurrenceConstraint
- A constraint specifying the amount of times a substring should be present within the test subject. It can be created by invoking static methods Once, Twice, Thrice, or Times(int) on the classes FluentAssertions.Exactly, FluentAssertions.AtLeast, FluentAssertions.MoreThan, FluentAssertions.AtMost, and FluentAssertions.LessThan. For example, FluentAssertions.Exactly.Times or FluentAssertions.LessThan.Twice.
- because
- A formatted phrase as is supported by System.String.Format(System.String,System.Object[]) explaining why the assertion is needed. If the phrase does not start with the word because, it is prepended automatically.
- becauseArgs
- Zero or more objects to format using the placeholders in because.
