2019-12-23 The following examples show how to use org.scalatest.Assertions . These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. Example 1.

They do not use the Java assert framework and therefore are always evaluated regardless of whether or not assertions are enabled. Update: Scala 2.8 has an annotation called elidable that will (when 2.8 is complete) allow one to remove method calls at compile time by setting a compiler flag.

This behavior is provided by the assert method defined in object Predef, whose members are implicitly imported into every Scala source file. ScalaTest provides a domain specific language (DSL) for expressing assertions in tests using the word should . MUnit provides a few ways to fail a test given a condition.

Lets say you have simple class that is using the Scala assert method: class Example { def test = { assert( (1+1) == 2, "Addition broken") } } When you enable the jvmassert compiler plugin, it will translate the previous example to: 2019-04-10 Step 3) Lets analyse expected output step by step: Consider all assert statements one by one: Now compare string1=" Junit" with string2=" Junit" with equals method of object class. Replacing assertEquals method from java.lang.Object.equals () method : So assertEquals (string1,string2) will return true.

在任何Scala程序中,您可以通过调用assert和传递Boolean表达式来编写断言,例如: val left = 2 val right = 1 assert(left == right) 如果传递的表达式是true,assert将正常返回。如果false,Scala assert将会突然完成AssertionError。 scala> (new ElementSpec).execute() A UniformElement - should have a width equal to the passed value - should have a height equal to the passed value - should throw an IAE if passed a negative width. The specs testing framework, an open source tool written in Scala by Eric Torreborre, also supports the BDD style of testing but with a different At the end of each test you should call assert to test that a condition has been satisfied; Using ScalaTest like this is similar to JUnit, so if you’re coming to Scala from Java, hopefully this looks very familiar. Now you can run these tests with the sbt test command. Skipping the first few lines of output, the result looks like this: Selecting testing styles for your project.
