Assert Throws Exception Scala at Olivia Quinlivan blog

Assert Throws Exception Scala. The body of the intercept assertion contains the code that should throw the exception. You need to implicitly pass a manifest for your exception class, like so: Assertresult to differentiate expected from actual values; We can use scalatest to test scenarios that throw exceptions, as well as to handle failures in try or future constructs. In scala, assertions are written using the assert method, which throws an assertionerror if the specified condition is. The assertthrows method also conveniently returns the caught exception, allowing further inspection or validation of its properties, such as the error message. In any scala program, you can. This method invokes the passed function. Intercept to ensure a bit of code throws an expected exception. The test passes if the code throws the expected. If the function throws an exception that's an instance of the specified type, this method returns that. If any other exception type (or no exception at all) is thrown, scalatest will raise a testfailedexception. Scalatest makes three assertions available by default in any style trait.
