Intercept and return an exception that's expected to be thrown by the passed function value.
Intercept and return an exception that's expected to
be thrown by the passed function value. The thrown exception must be an instance of the
type specified by the type parameter of this method. This method invokes the passed
function. If the function throws an exception that's an instance of the specified type,
this method returns that exception. Else, whether the passed function returns normally
or completes abruptly with a different exception, this method throws TestFailedException.
Note that the type specified as this method's type parameter may represent any subtype of
AnyRef, not just Throwable or one of its subclasses. In
Scala, exceptions can be caught based on traits they implement, so it may at times make sense
to specify a trait that the intercepted exception's class must mix in. If a class instance is
passed for a type that could not possibly be used to catch an exception (such as String,
for example), this method will complete abruptly with a TestFailedException.

Executes the block of code passed as the second parameter, and, if it
completes abruptly with a ModifiableMessage exception,
prepends the "clue" string passed as the first parameter to the beginning of the detail message

character, one space will be added
between it and the existing detail message (unless the detail message is
not defined).
This method allows you to add more information about what went wrong that will be reported when a test fails. Here's an example:
withClue("(Employee's name was: " + employee.name + ")") {
intercept[IllegalArgumentException] {
employee.getTask(-1)
}
}
If an invocation of intercept completed abruptly with an exception, the resulting message would be something like:
(Employee's name was Bob Jones) Expected IllegalArgumentException to be thrown, but no exception was thrown

Trait that can be mixed into a
Suiteto disable the lone implicit conversion provided by default in traitAssertions, which traitSuiteextends.Currently there is just one implicit conversion provided by default in
Suite, the one that adds a===method to anything. If more default implicits are added toSuitein future versions of ScalaTest, they will be added here as well so that this trait will disable all of them.This trait can be used to quickly solve a problem in which ScalaTest's default implicit conversion is clashing with those of some other library you need to use in your tests. After mixing in this trait, like this:
class MySuite extends FunSuite with NonImplicitAssertions { // ... }You can write tests using
assert(without triple equals),expect, andintercept:
