Variable capture

Type Declaration

• • <T extends {}, M extends string | number | symbol>(
        obj: T,
        method: M,
        impl?: (this: T, ...a: any[]) => any,
    ): CaptureResultsMethod<T, M>

  • Intercept calls to a method to track the arguments, call site, and return/throw status, and replace the implementation.

    By default, the method is set to a no-op. To retain the method behavior, pass the current value of the method as the third argument. For example:

    const results = t.capture(obj, 'foo', obj.foo)
    Copy

    Automatically restores at t.teardown() if the @tapjs/after plugin is not disabled. Otherwise, it is important to call the restore() method on the returned function when you are done capturing.

    Parameters

    • obj: T
