The type constructor Assert is defined as a contravariant, which means that Assert[Person] is indeed a subtype of Assert[Employee]. Therefore, the list of Assert can contain instances of either Assert[Employee] or Assert[Person]:

It's easy to read and easy to write and looks like this: 23 should be >= (12) Even if you know nothing Scala test Future Failure. Asynchronous testing, You can instead map those assertions onto the Future and return the Future import scala.concurrent. Assertion]] Assert class provides a set of assertion methods useful for writing tests. assertArrayEquals() method checks that two object arrays are equal or not.

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. ScalaTest supports different styles of testing, each designed to address a particular set of needs. To help you find the best-fit styles for your project, this page will describe the intended use cases for each option. 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: Getting started with JUnit 4 and Scala.

28 May 2018 For Scala, Peter Niederwieser himself wrote a mini library called Expecty around 2012 that implements power assert. This is a good news and The Assertions API is used to verify that global statistics like response time or number of failed requests matches expectations for a whole simulation. chisel3 3.4.2 - chisel3.assert.

Scala的博大很大程度上在于它的对象系统。Scala中所有的值都是对象，就这一意义而言Scala是门纯粹的语言；基本类型和组合类型没有区别。Scala也提供了mixin的特性允许更多正交地、细粒度地构造一些在编译时受益于静态类型检测的可被灵活组装的模块。 14 Assertions and Tests.

The assert macro In any Scala program, you can write assertions by invoking assert and passing in a Boolean expression, such as: val left = 2 val right = 1 assert(left == right) If the passed expression is true, assert will return normally. If false, Scala's assert will complete abruptly with an AssertionError.
