Trait extended by matcher objects, which may appear after the word be, that can match a value of the specified type. The value to match is passed to the BeMatcher's apply method. The result is a MatchResult. A BeMatcher is, therefore, a function from the specified type, T, to a MatchResult.

The result of a Boolean property match operation, such as one performed by a BePropertyMatcher, which contains one field that indicates whether the match succeeded (i.e., the Boolean property was true) and one field that provides the name of the property.

Trait extended by matcher objects, which may appear after the word be, that can match against a Boolean property. The match will succeed if and only if the Boolean property equals true. The object containing the property, which must be of the type specified by the BePropertyMatcher's type parameter T, is passed to the BePropertyMatcher's apply method. The result is a BePropertyMatchResult. A BePropertyMatcher is, therefore, a function from the specified type, T, to a BePropertyMatchResult.

The result of a property match operation such as one performed by a HavePropertyMatcher, which contains one field that indicates whether the match succeeded (i.e., the property had its expected value), one field that provides the name of the property, and two fields giving the expected and actual values. HavePropertyMatchResult's type parameter, P, specifies the type of the property.

Trait extended by matcher objects, which may appear after the word have, that can match against a property of the type specified by the HavePropertyMatcher's second type parameter P. HavePropertyMatcher's first type parameter, T, specifies the type that declares the property. The match will succeed if and only if the value of the property equals the specified value. The object containing the property is passed to the HavePropertyMatcher's apply method. The result is a HavePropertyMatchResult[P]. A HavePropertyMatcher is, therefore, a function from the specified type, T, to a HavePropertyMatchResult[P].

The result of a match operation, such as one performed by a Matcher or BeMatcher, which contains one field that indicates whether the match succeeded and four fields that provide failure messages to report under different circumstances.

Trait extended by objects that can match a value of the specified type. The value to match is passed to the matcher's apply method. The result is a MatchResult. A matcher is, therefore, a function from the specified type, T, to a MatchResult.

This trait is part of the ScalaTest matchers DSL. Please see the documentation for ShouldMatchers or MustMatchers for an overview of the matchers DSL.

Trait that provides a domain specific language (DSL) for expressing assertions in tests using the word must. (If you prefer the word should, you can alternatively mix in trait ShouldMatchers.) For example, if you mix MustMatchers into a suite class, you can write an equality assertion in that suite like this:

 object must equal (3)

Companion object that facilitates the importing of MustMatchers members as an alternative to mixing it the trait. One use case is to import MustMatchers members so you can use them in the Scala interpreter:

 $scala -classpath scalatest.jar
 Welcome to Scala version 2.7.3.final (Java HotSpot(TM) Client VM, Java 1.5.0_16).
 Type in expressions to have them evaluated.
