Runs once after all test cases and after all suite-local fixtures have been tear down.

Runs after each individual test case.

Asserts that two elements are equal using == equality.

The "expected" value (second argument) must have the same type or be a subtype of the "obtained" value (first argument). For example:

 assertEquals(Option(1), Some(1)) // OK
 assertEquals(Some(1), Option(1)) // Error: Option[Int] is not a subtype of Some[Int]

Use assertEquals[Any, Any](a, b) as an escape hatch to compare two values of different types. For example:

 val a: Either[List[String], Int] = Right(42)
 val b: Either[String, Int]       = Right(42)
 assertEquals[Any, Any](a, b) // OK
 assertEquals(a, b) // Error: Either[String, Int] is not a subtype of Either[List[String], Int]

Asserts that two doubles are equal to within a positive delta. If the expected value is infinity then the delta value is ignored. NaNs are considered equal: assertEquals(Double.NaN, Double.NaN, *) passes.

Asserts that two floats are equal to within a positive delta. If the expected value is infinity then the delta value is ignored. NaNs are considered equal: assertEquals(Float.NaN, Float.NaN, *) passes.

Asserts that an IO returns an expected value.

The "returns" value (second argument) must have the same type or be a subtype of the one "contained" inside the IO (first argument). For example:

 assertIO(IO(Option(1)), returns = Some(1)) // OK
 assertIO(IO(Some(1)), returns = Option(1)) // Error: Option[Int] is not a subtype of Some[Int]

The "clue" value can be used to give extra information about the failure in case the assertion fails.

Asserts that a SyncIO returns an expected value.

The "returns" value (second argument) must have the same type or be a subtype of the one "contained" inside the SyncIO (first argument). For example:

 assertSyncIO(SyncIO(Option(1)), returns = Some(1)) // OK
 assertSyncIO(SyncIO(Some(1)), returns = Option(1)) // Error: Option[Int] is not a subtype of Some[Int]

The "clue" value can be used to give extra information about the failure in case the assertion fails.

Runs once before all test cases and before all suite-local fixtures are setup. An error in this method aborts the test suite.

Runs before each individual test case. An error in this method aborts the test case.

Intercepts a Throwable being thrown inside the provided IO.

Intercepts a Throwable with a certain message being thrown inside the provided IO.

Intercepts a Throwable with a certain message being thrown inside the provided SyncIO.

Intercepts a Throwable being thrown inside the provided SyncIO.

Functinonal fixtures that can be reused for individual test cases or entire suites.

Implicitly create a TestOptions given a test name. This allows writing test("name") { ... } even if test accepts a TestOptions
