The Importance of Frontend Tests

Oct 13, 2025 by wbrum.org 6 views

Background

As we continue to grow and evolve as a team, it's essential to streamline our processes and reduce manual work wherever possible. One area that requires attention is the review of frontend Pull Requests (PRs) by Software Leads. Currently, this process involves a significant amount of manual effort, which can be time-consuming and prone to errors. By incorporating frontend tests into our GS onboarding process, we can automate this review process, reducing the workload of our Software Leads and ensuring that our codebase remains of high quality.

The Importance of Frontend Tests

Frontend tests play a crucial role in ensuring the stability and reliability of our application. They enable us to verify that our code behaves as expected, catch bugs early in the development cycle, and prevent regressions. By adding frontend tests to our GS onboarding process, we can:

Improve code quality: Frontend tests help us catch errors and bugs early, ensuring that our code is stable and reliable.
Reduce manual work: By automating the review process, we can free up time for our Software Leads to focus on more critical tasks.
Enhance collaboration: Frontend tests provide a clear understanding of the expected behavior of our code, facilitating collaboration among team members.

Requirements

To add frontend tests to our GS onboarding process, we need to:

Add frontend tests: We will use Deno tests to write and run our frontend tests.

Using Deno Tests

Deno tests are a popular choice for writing and running frontend tests. They offer a simple and intuitive API, making it easy to write and maintain tests. Here are some benefits of using Deno tests:

Easy to write: Deno tests have a simple and intuitive API, making it easy to write and maintain tests.
Fast execution: Deno tests execute quickly, providing fast feedback on test results.
Flexible: Deno tests can be used to test a wide range of frontend code, including JavaScript, TypeScript, and HTML.

Setting Up Deno Tests

To set up Deno tests, we need to:

Install Deno: We need to install Deno on our machine to run our tests.
Create a test file: We need to create a test file to write our tests.
Write tests: We need to write our tests using the Deno test API.

Writing Deno Tests

Writing Deno tests is a straightforward process. Here's an example of how to write a simple test using Deno:

import { test } from 'https://deno.land/std/testing/mod.ts';

test('test example', () => {
  const result = 2 + 2;
  assertEquals(result, 4);
});

In this example, we import the test function from the deno.land/std/testing/mod.ts module. We then define a test function that takes a string argument, which is the name of the test. Inside the test function, we write our test code, which in this case is a simple arithmetic operation.

Running Deno Tests

To run our Deno tests, we need to:

Navigate to the test file: We need to navigate to the test file in our terminal.
Run the test command: We need to run the test command, which is deno test.

Benefits of Adding Frontend Tests

Adding frontend tests to our GS onboarding process offers several benefits, including:

Improved code quality: Frontend tests help us catch errors and bugs early, ensuring that our code is stable and reliable.
Reduced manual work: By automating the review process, we can free up time for our Software Leads to focus on more critical tasks.
Enhanced collaboration: Frontend tests provide a clear understanding of the expected behavior of our code, facilitating collaboration among team members.

Conclusion

Adding frontend tests to our GS onboarding process is a crucial step in enhancing efficiency and quality. By using Deno tests, we can automate the review process, reduce manual work, and improve code quality. We can also enhance collaboration among team members by providing a clear understanding of the expected behavior of our code. By following the steps outlined in this article, we can successfully add frontend tests to our GS onboarding process and reap the benefits of improved code quality, reduced manual work, and enhanced collaboration.

Future Work

In the future, we can:

Expand test coverage: We can expand our test coverage to include more frontend code, such as JavaScript, TypeScript, and HTML.
Improve test efficiency: We can improve the efficiency of our tests by using techniques such as test parallelization and test optimization.
Enhance collaboration: We can enhance collaboration among team members by providing a clear understanding of the expected behavior of our code and facilitating communication among team members.
