This user guide will help you get rolling quickly with ScalaTest. First a brief orientation:

• The central concept in ScalaTest is the suite, a collection of zero to many tests.
• A test can be anything with a name that can start and either succeed, fail, be pending, or canceled.
• The central unit of composition in ScalaTest is Suite, which represents a suite of tests.
• Trait Suite declares run and other “lifecycle” methods that define a default way to write and run tests.
• These lifecycle methods can be overridden to customize how tests are written and run.
• ScalaTest offers style traits that extend Suite and override lifecycle methods to support different testing styles.
• It provides mixin traits that override lifecycle methods of the style traits to address particular testing needs.
• You define test classes by composing Suite style and mixin traits.
• You define test suites by composing Suite instances.

To include ScalaTest in your sbt project, simply add this line:

libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test"

To include ScalaTest in your Maven project, use:

<dependency>
  <groupId>org.scalatest</groupId>
  <artifactId>scalatest_2.10</artifactId>
  <version>2.2.4</version>
  <scope>test</scope>
</dependency>

For other ways to include ScalaTest in your project, see Running your tests.

Using ScalaTest on your project is as easy as 1, 2, 3:

1. Select your testing styles
2. Define your base classes
3. Start writing tests
