    Interface IStrictlyOp<R>

    Represents an interface that provides assertion operations based on the strict comparisons.

    interface IStrictlyOp<R> {
        eq: EqualFn<R>;
        equal: EqualFn<R>;
        equals: EqualFn<R>;
        false: AssertFn<R>;
        not: IStrictlyOp;
        true: AssertFn<R>;
    }

    Type Parameters

    • R

      The type of the result of the operation.

    Properties

    eq: EqualFn<R>

    Performs an equality check between the actual and expected values, throwing an AssertionFailure with the given message when the actual value is not equal to the expected value. The default equality check is a loose (==) equality check, to perform a strict equality check (===), use the IStrictlyOp.equal (strictly.equal) operations and when comparing complex objects, use the deep equality operations provided by the IDeepOp.equal (deep.equal) operations or (deep.strictly.equal) for deep strict equality checks. IStrictlyOp.eq (strictly.eq) operations.

    The type of the expected value.

    The expected value.

    The message to display if the values are strictly equal.

    AssertionFailure - If the expected and actual values are strictly equal.

    assert.eq(1, 1); // Passes
    assert.eq("a", "a"); // Passes
    assert.eq(true, true); // Passes
    assert.eq(false, false); // Passes
    assert.eq(null, null); // Passes
    assert.eq(undefined, undefined); // Passes
    assert.eq(0, 0); // Passes
    assert.eq(-0, -0); // Passes
    assert.eq(+0, +0); // Passes
    assert.eq(0n, 0n); // Passes
    assert.eq("", ""); // Passes
    assert.eq(Symbol(), Symbol()); // Passes
    assert.eq([], []); // Throws AssertionError
    assert.eq([1, 2], [1, 2]); // Throws AssertionError

    equals: EqualFn<R>

    Performs an equality check between the actual and expected values, throwing an AssertionFailure with the given message when the actual value is not equal to the expected value.

    The expected value.

    The message to display if the values are strictly equal.

    AssertionFailure - If the expected and actual values are strictly equal.

    assert.equals(1, 1); // Passes
    assert.equals("a", "a"); // Passes

    assert.equals(false, false); // Passes
    assert.equals(null, null); // Passes

    assert.equals(Symbol(), Symbol()); // Passes
    assert.equals([], []); // Throws AssertionError
    assert.equals([1, 2], [1, 2]); // Throws AssertionError
    false: AssertFn<R>

    Asserts that the value is strictly equal to false.

    The expected value.

    Optional. The message to display if the assertion fails.

    The result of the operation, which will generally be the existing IAssertScope.that object.

    AssertionFailure - If the current IScopeContext.value is not strictly equal to false.

    not: IStrictlyOp

    Negates any performed evaluations that are performed in the assertion chain.

    This operation applies a stateful change to the evaluation chain, meaning that subsequent operations that would normally fail will pass without the need for them to "implement" any knowledge about the not operation. You may call not multiple times to negate the negation.

    import { assert } from "@nevware21/tripwire";

    expect(true).not.ok(); // Fails
    expect(false).not.ok(); // Passes
    expect(true).not.not.ok(); // Passes
    expect(false).not.not.ok(); // Fails
    true: AssertFn<R>

    Asserts that the value is strictly equal to true.

    The expected value.

    Optional. The message to display if the assertion fails.

    The result of the operation, which will generally be the existing IAssertScope.that object.

    AssertionFailure - If the current IScopeContext.value is not strictly equal to true.
