fun <E, T : Result<E>> Expect<T>.toBeASuccess(): Expect<E> (source)
Expects that the subject of this expectation (a Result) is a success (Result.isSuccess)
and returns an Expect for the inner type E.
expect(Result.success(10))
.toBeASuccess() // subject is now of type Int (actually 10)
.toEqual(1)
fails { // because sub-expectation fails
expect(Result.success(10))
.toBeASuccess() // subject is now of type Int (actually 10)
.toBeLessThan(5) // fails
.toBeGreaterThan(12) // not reported because toBeLessThan already fails
// use `.toBeASuccess { ... }` if you want that all expectations are evaluated
}
fails { // because it was a Failure
expect(Result.failure<Int>(ArithmeticException()))
.toBeASuccess() // fails
.toBeGreaterThan(12) // not reported because toBeLessThan already fails
// use `.toBeASuccess { ... }` if you want that all expectations are evaluated
}Return
The newly created Expect if the given assertion is a success.

fun <E, T : Result<E>> Expect<T>.toBeASuccess(assertionCreator: Expect<E>.() -> Unit): Expect<T> (source)
Expects that the subject of this expectation (a Result) is a success (Result.isSuccess) and
that it holds all assertions the given assertionCreator creates.
expect(Result.success(10)).toBeASuccess { // subject within this block is of type Int (actually 10)
toEqual(10)
toBeLessThan(15)
} // subject here is back to type Result<Int>
fails { // because sub-expectation fails
expect(Result.success(10)).toBeASuccess {
toBeGreaterThan(15) // fails
toBeLessThan(5) // still evaluated even though toBeGreaterThan already fails
// use `.toBeASuccess.` if you want a fail fast behaviour
}
}
fails { // because it was a Failure, but since we use a block...
expect(Result.failure<Int>(ArithmeticException())).toBeASuccess {
toBeGreaterThan(12) // ...reporting mentions that subject was expected `to be greater than: 12`
// use `.toBeASuccess.` if you want a fail fast behaviour
}
}Return
an Expect for the subject of this expectation.
