insomnia.response.to.be.error;
});

insomnia.test('withBody', () => {
	insomnia.response.to.be.withBody;
});

insomnia.test('to be json', () => {
insomnia.response.to.not.be.json;
});

insomnia.test('not error', () => {
insomnia.response.to.be.error;
});

insomnia.test("ok", function () {
	insomnia.response.to.not.be.ok;
	insomnia.expect(insomnia.response.hehe).to.be.ok;
	insomnia.response.to.be.ok;
});

insomnia.test("have 204", function () {
	insomnia.response.to.not.have.status(200);
});

insomnia.test("have 204", function () {
	insomnia.response.to.have.jsonBody("args");
});

insomnia.test("have header", function () {
	insomnia.response.to.have.header("Content-Type");
});

insomnia.test("have body", function () {
	insomnia.response.to.have.body("123");
});

insomnia.test("have body", function () {
	insomnia.response.to.have.jsonSchema({
      type: 'object',
      properties: {
        key: { type: 'integer' },
      },
      required: ['arg'],
      additionalProperties: true,
    });
});

const resp = insomnia.response.json();
insomnia.test("id not null", function () {
	insomnia.expect(resp.id).to.be.not.exists;
});
