What is FlatSpec?

What is FlatSpec?

Trait FlatSpec is so named because your specification text and tests line up flat against the left-side indentation level, with no nesting needed. FlatSpec ‘s no-nesting approach contrasts with traits FunSpec and WordSpec , which use nesting to reduce duplication of specification text.

  5. In the source code, right-click CubeCalculatorTest and select Run ‘CubeCalculatorTest’.

What is Scala testing?

The Scala Penetrometer is an extremely useful field tool for measuring bearing capacity and for correlation to CBR; and with its portability, speed and ability to penetrate down to 6 meters or more with extension rods, the Scala is the perfect tool for profiling soil strength at depth.

What is spec in Scala?

A Spec contains describe clauses and tests. You define a describe clause with describe , and a test with it . A describe clause names, or gives more information about, the subject (class or other entity) you are specifying and testing. In the previous example, “A Stack” is the subject under specification and test.

What is FunSpec?

In a FunSpec , you combine tests with text that specifies the behavior being tested. You can describe the subject being specified and tested with describe clauses and place text that describes the behavior expected of the subject in it clauses. The code of the test appears in curly braces after the it and its text.

What is FunSuite?

By learning to use FunSuite , simple assertions, and the BeforeAndAfter trait, you can become productive in the TDD style of ScalaTest very quickly. You can then learn and use more of ScalaTest over time. In a FunSuite , tests are function values. ( The “ Fun ” in FunSuite stands for function.)

What is a Clegg Hammer?

The Clegg Impact Hammer (Winter Sports, Cricket and Equestrian) is used to measure the hardness or shock absorption properties of a turf surface. It can also be used to evaluate ball bounce and pace on cricket pitches and to ensure safety and consistency on equestrian surfaces.

What is Scala FunSuite?

FunSuite is a Scala testing library with the following goals: Reuse JUnit: FunSuite is implemented as a JUnit runner and tries to build on top of existing JUnit functionality where possible. Any tool that knows how to run a JUnit test suite knows how to run FunSuite, including IDEs like IntelliJ.

How much testing is enough?

No testing is enough, but we can maximize the test coverage by using a smart test approach. Smart testing optimizes the design verification process for maximum possible coverage, given the product cycle time, while keeping costs at or below the defined target.

How do you use a Clegg Hammer?

Raise the hammer with one hand until the white indicator ring is level with the top of the guide tube. Make sure the cable is free and will not snag as the hammer falls; then drop the hammer cleanly. Observe the meter reading.

How are tests defined in a ScalaTest project?

In ScalaTest, you define tests inside classes that extend a style class such as AnyFlatSpec (though in practice you’d usually directly extend a base class defined for your project, which extends a ScalaTest style class):

Which is the best testing library for Scala?

Scalatest is just one among many testing libraries for scala but it’s quite complete and a lot of people use it so it’s a good choice for starting out with. Scalatest support many different testing styles under the same testing framework, for example: XUnit – testing style made popular by tools such as JUnit, NUnit, etc.

What makes a test in anyflatspec a test?

2. Each test in a AnyFlatSpec is composed of a sentence that specifies a bit of required behavior and a block of code that tests it. The sentence needs a subject, such as “A Stack”; a verb, either should, must, or can; and the rest of the sentence.

How to test for text to match in Scala?

Go to the root of the project and enter sbt then testOnly Use testOnly — -z “text to match”. Only test cases matching “text to match” will be run. In the following example, only the test case whose text matches “should pop values” in class SampleFlatSpec will be run:
