class BeWord

[source: org/scalatest/matchers/Matchers.scala]

final class BeWord
extends AnyRef
This class is part of the ScalaTest matchers DSL. Please see the documentation for ShouldMatchers or MustMatchers for an overview of the matchers DSL.

Class BeWord contains an apply method that takes a Symbol, which uses reflection to find and access a Boolean property and determine if it is true. If the symbol passed is 'empty, for example, the apply method will use reflection to look for a public Java field named "empty", a public method named "empty", or a public method named "isEmpty". If a field, it must be of type Boolean. If a method, it must take no parameters and return Boolean. If multiple candidates are found, the apply method will select based on the following algorithm:

FieldMethod"is" MethodResult
   Throws TestFailedException, because no candidates found
  isEmpty()Invokes isEmpty()
 empty() Invokes empty()
 empty()isEmpty()Invokes empty() (this can occur when BeanProperty annotation is used)
empty  Accesses field empty

Method Details
def <[T](right : T)(implicit view$1 : (T) => scala.Ordered[T]) : Matcher[T]
This method enables the following syntax:
     result should be < (7)
                      ^
     

Note that the less than operator will be invoked on be in this expression, not on a result of passing be to should, as with most other operators in the matchers DSL, because the less than operator has a higher precedence than should. Thus in the above case the first expression evaluated will be be < (7), which results in a matcher that is passed to should.

This method also enables the following syntax:

     result should not (be < (7))
                           ^
     

def >[T](right : T)(implicit view$2 : (T) => scala.Ordered[T]) : Matcher[T]
This method enables the following syntax:
     result should be > (7)
                      ^
     

Note that the greater than operator will be invoked on be in this expression, not on a result of passing be to should, as with most other operators in the matchers DSL, because the greater than operator has a higher precedence than should. Thus in the above case the first expression evaluated will be be > (7), which results in a matcher that is passed to should.

This method also enables the following syntax:

     result should not (be > (7))
                           ^
     

def <=[T](right : T)(implicit view$3 : (T) => scala.Ordered[T]) : Matcher[T]
This method enables the following syntax:
     result should be <= (7)
                      ^
     

Note that the less than or equal to operator will be invoked on be in this expression, not on a result of passing be to should, as with most other operators in the matchers DSL, because the less than or equal to operator has a higher precedence than should. Thus in the above case the first expression evaluated will be be <= (7), which results in a matcher that is passed to should.

This method also enables the following syntax:

     result should not (be <= (7))
                           ^
     

def >=[T](right : T)(implicit view$4 : (T) => scala.Ordered[T]) : Matcher[T]
This method enables the following syntax:
     result should be >= (7)
                      ^
     

Note that the greater than or equal to operator will be invoked on be in this expression, not on a result of passing be to should, as with most other operators in the matchers DSL, because the greater than or equal to operator has a higher precedence than should. Thus in the above case the first expression evaluated will be be >= (7), which results in a matcher that is passed to should.

This method also enables the following syntax:

     result should not (be >= (7))
                           ^
     

def ===(right : Any) : Matcher[Any]
This method enables the following syntax:
     result should be === (7)
                      ^
     

Note that the === operator will be invoked on be in this expression, not on a result of passing be to should, as with most other operators in the matchers DSL, because the ===n operator has a higher precedence than should. Thus in the above case the first expression evaluated will be be === (7), which results in a matcher that is passed to should.

This method also enables the following syntax:

     result should not (be === (7))
                           ^
