Assert

eff AssertSource

An effect used to perform assertions during program execution.

Operations

def assert(cond: Bool, msg: RichString): Unit \ Assert Source

Asserts that the given condition cond is true with a message msg.

Definitions

def assertEmpty(ma: m[a]): Unit \ Assert + Aef[m] with Foldable[m], ToString[m[a]] Source

Asserts that the given foldable ma is empty.

def assertEq(expected: { expected = a }, actual: a): Unit \ Assert with Eq[a], ToString[a] Source

Asserts that the given values expected and actual are equal.

def assertEqWithMsg(expected: { expected = a }, actual: a, msg: String): Unit \ Assert with Eq[a] Source

Asserts that the given values expected and actual are equal with the given message msg.

def assertErr(r: Result[e, a]): Unit \ Assert Source

Asserts that the given Result r is Err(e).

def assertFalse(cond: Bool): Unit \ Assert Source

Asserts that the given condition cond is false.

def assertFalseWithMsg(cond: Bool, msg: String): Unit \ Assert Source

Asserts that the given condition cond is false with the given message msg.

def assertMemberOf(x: a, ma: m[a]): Unit \ Assert + Aef[m] with Foldable[m], Eq[a], ToString[a], ToString[m[a]] Source

Asserts that the given element x is a member of the given foldable ma.

def assertNeq(unexpected: { unexpected = a }, actual: a): Unit \ Assert with Eq[a], ToString[a] Source

Asserts that the given values unexpected and actual are not equal.

def assertNeqWithMsg(unexpected: { unexpected = a }, actual: a, msg: String): Unit \ Assert with Eq[a] Source

Asserts that the given values unexpected and actual are not equal with the given message msg.

def assertNonEmpty(ma: m[a]): Unit \ Assert + Aef[m] with Foldable[m], ToString[m[a]] Source

Asserts that the given foldable ma is non-empty.

def assertNone(o: Option[a]): Unit \ Assert Source

Asserts that the given Option o is None.

def assertOk(r: Result[e, a]): Unit \ Assert Source

Asserts that the given Result r is Ok(v).

def assertSome(o: Option[a]): Unit \ Assert Source

Asserts that the given Option o is Some(v).

def assertTrue(cond: Bool): Unit \ Assert Source

Asserts that the given condition cond is true.

def assertTrueWithMsg(cond: Bool, msg: String): Unit \ Assert Source

Asserts that the given condition cond is true with the given message msg.

def fail(msg: String): Unit \ Assert Source

Unconditionally fails with the given message msg.

def handle(f: a -> b \ ef): a -> b \ (ef - Assert) + IO Source

Handles the Assert effect of the given function f by throwing exceptions on assertion failures.

In other words, re-interprets the Assert effect using the IO effect.

def handleWithLogger(f: a -> b \ ef): a -> b \ (ef - Assert) + Logger Source

Handles the Assert effect by logging assertion failures using the Logger effect.

Assertions continue execution after logging the assertion failure.

def handleWithNoOp(f: a -> b \ ef): a -> b \ ef - Assert Source

Handles the Assert effect by ignoring all assertions (no-op).

def handleWithPrompt(f: a -> b \ ef): a -> b \ (ef - Assert) + IO + Sys Source

Handles the Assert effect by prompting the user whether to continue execution.

When an assertion fails, prints the assertion failure and asks the user if they want to continue. If the user chooses not to continue, the program throws an exception.

def handleWithStdErr(f: a -> b \ ef): a -> b \ (ef - Assert) + IO + Sys Source

Handles the Assert effect by printing assertion failures to stderr.

Assertions continue execution after printing the assertion failure.

def handleWithStdOut(f: a -> b \ ef): a -> b \ (ef - Assert) + IO + Sys Source

Handles the Assert effect by printing assertion failures to stdout.

Assertions continue execution after printing the assertion failure.

def runWithIO(f: Unit -> a \ ef): a \ (ef - Assert) + IO Source

Runs the Assert effect of the given function f by throwing exceptions on assertion failures.

In other words, re-interprets the Assert effect using the IO effect.

def success(msg: String): Unit \ Assert Source

Unconditionally succeeds with the given message msg.
