ShouldMatchersForJUnit

trait ShouldMatchersForJUnit extends ShouldMatchers with AssertionsForJUnit

Trait that makes ScalaTest's ShouldMatchers DSL syntax available for use with JUnit.

The assertion methods provided in this trait look and behave exactly like the ones in ShouldMatchers, except instead of throwing TestFailedException they throw JUnitTestFailedError, which extends junit.framework.AssertionFailedError.

JUnit 3 (release 3.8 and earlier) distinguishes between failures and errors. If a test fails because of a failed assertion, that is considered a failure. If a test fails for any other reason, either the test code or the application being tested threw an unexpected exception, that is considered an error. The way JUnit 3 decides whether an exception represents a failure or error is that only thrown junit.framework.AssertionFailedErrors are considered failures. Any other exception type is considered an error. The exception type thrown by the JUnit 3 assertion methods declared in junit.framework.Assert (such as assertEquals, assertTrue, and fail) is, therefore, AssertionFailedError.

In JUnit 4, AssertionFailedError was made to extend java.lang.AssertionError, and the distinction between failures and errors was essentially dropped. However, some tools that integrate with JUnit carry on this distinction, so even if you are using JUnit 4 you may want to use this ShouldMatchersForJUnit trait instead of plain-old ScalaTest ShouldMatchers.

To use this trait in a JUnit 3 TestCase, you can mix it into your TestCase class, like this:

import junit.framework.TestCase
import org.scalatest.junit.ShouldMatchersForJUnit

class MyTestCase extends TestCase with ShouldMatchersForJUnit {
def testSomething() { "hello, world!" should startWith ("hello") }
// ... }

You can alternatively import the methods defined in this trait.

import junit.framework.TestCase
import org.scalatest.junit.ShouldMatchersForJUnit._

class MyTestCase extends TestCase {
def testSomething() { "hello, world!" should startWith ("hello") }
// ... }

For details on the importing approach, see the documentation for the ShouldMatchersForJUnit companion object. For the details on the ShouldMatchersForJUnit syntax, see the Scaladoc documentation for org.scalatest.matchers.ShouldMatchers

    Implicit conversion from Any to Equalizer, used to enable assertions with === comparisons.

    Implicit conversion from Any to Equalizer, used to enable assertions with === comparisons.

    For more information on this mechanism, see the documentation for Equalizer.

    Because trait Suite mixes in Assertions, this implicit conversion will always be available by default in ScalaTest Suites. This is the only implicit conversion that is in scope by default in every ScalaTest Suite. Other implicit conversions offered by ScalaTest, such as those that support the matchers DSL or invokePrivate, must be explicitly invited into your test code, either by mixing in a trait or importing the members of its companion object. The reason ScalaTest requires you to invite in implicit conversions (with the exception of the implicit conversion for === operator) is because if one of ScalaTest's implicit conversions clashes with an implicit conversion used in the code you are trying to test, your program won't compile. Thus there is a chance that if you are ever trying to use a library or test some code that also offers an implicit conversion involving a === operator, you could run into the problem of a compiler error due to an ambiguous implicit conversion. If that happens, you can turn off the implicit conversion offered by this convertToEqualizer method simply by overriding the method in your Suite subclass, but not marking it as implicit:

    // In your Suite subclass
    override def convertToEqualizer(left: Any) = new Equalizer(left)
    

    left

    the object whose type to convert to Equalizer.

    This method enables the following syntax:

    The left should equal (right) syntax works by calling == on the left value, passing in the right value, on every type except arrays. If both left and right are arrays, deep will be invoked on both left and right before comparing them with ==. Thus, even though this expression will yield false, because Array's equals method compares object identity:

    Array(1, 2) == Array(1, 2) // yields false
    

    The following expression will not result in a TestFailedException, because ScalaTest will compare the two arrays structurally, taking into consideration the equality of the array's contents:

    Array(1, 2) should equal (Array(1, 2)) // succeeds (i.e., does not throw TestFailedException)
    

    If you ever do want to verify that two arrays are actually the same object (have the same identity), you can use the be theSameInstanceAs syntax.
