Import from this module

import { test } from 'demeter';

Run a test

    t.assert(true);
})
.test('assert 2 should fail', t=>{
    t.assert(false);
}).run();

Assertions

The message argument is an optional argument.

t.assert(boolean, message), t.ok(boolean, message)

Throw if boolean is false.

t.ok(boolean, message), t.ok(boolean, message)

Throw if boolean is false. Just like t.assert().

t.not(boolean, message)

Throw if boolean is true.

t.equal(value1, value2, message)

Throw if value1 is not equal to value2. This is a strict equal, or in other words t.equal() uses (===) the Identity operator

t.equalish(value1, value2, message)

Throw if value1 is not equal to value2. This is a non-strict equal. t.equalish() converts value types using (==).

t.notEqual(value1, value2, message)

Throw if value1 is equal to value2 using strict comparison.

t.notEqualish(value1, value2, message)

Throw if value1 is equal to value2 using non-strict comparison.

t.fail(message)

Just throw right away if t.fail() is called.

t.deepEqual(object1, object2, message)

Throw if object1 is not deeply equal to object2 using strict comparison.

t.deepEqual(object1, object2, message)

Throw if object1 is not deeply equal to object2 using non-strict comparison.
