assert.pass(assertion);

Called every time assertion passes.

Default implementation does nothing.

This method can be overridden by test runners to keep track of how many assertions have passed. Unless you're writing an integration for Sinon into a test runner, you won't need this.

See: https://github.com/sinonjs/sinon/issues/2657 for idea on replacing it

Example using test framework

import tap from "tap";
import * as sinon from "sinon";

tap.test("assert.pass - always succeeds", (t) => {
  t.doesNotThrow(() => {
    sinon.assert.pass("test assertion");
  }, "pass should not throw");

  t.end();
});

tap.test("assert.pass - can be called without arguments", (t) => {
  t.doesNotThrow(() => {
    sinon.assert.pass();
  }, "pass should work without arguments");

  t.end();
});
