How to unit test code inside validate method nuxtjs vuejs jest

Question

I have code inside validate method if condition true it returns true else false. I want to test that code. Is there any way to do it.

Answer 1

So usually asyncData method and validate method are part of nuxt not vuejs and can't be tested usually but we do want to test it if it was possible.

Why test validate : As we are working on a long project we want to test it if every condition works as expected, someone's change didn't hinder the working of this method and thus i came around with solution to call that method manually and pass parameters to it accordingly.

// example.vue
validate({ params, query }) {
    if (params.includes("abc" && query["something"])) {
      return true;
    } else {
      return false;
    }
  }

// example.test.js
import index from "example.vue"

describe("test", () => {
  it("Check validate method", async () => {
    // Check when query present
    const params = {
      abc: "abc"
    };
    const query = {
      something: "abc"
    };
    const validate = Index.validate({ params, $constants, query });
    expect(validate).toBe(true); // or false
  });
});
