It’s Never Been Better to Get Started with Cypress Web Tests

If your project could at all be described as a web application, your UX pipeline would likely benefit from adopting Cypress. Beating out Selenium on speed as well as breadth of testing tools, Cypress provides automated testing of your website’s critical features in a matter of minutes. A testing framework built on top of many

Shallow Testing Hooks with Enzyme

Hooks significantly simplify your code, and you can use them within an existing React codebase that otherwise uses classes. And it’s easy to dive right into using hooks – until you try to test your fancy new components.

Taking Elm for a Test Drive

Elm emerged on the scene in early 2012 as a strongly-typed, functional language that compiles down to Javascript. With its architecture and type system, it claims to provide bulletproof guardrails to help developers build systems that are highly reliable, with “no runtime exceptions in practice”. Elm prides itself on having a low barrier of entry

Introducing Wallaby – Concurrent Feature Tests for Elixir and Phoenix

Feature tests are one of the best ways to ensure reliability and consistency for web applications. But, as we’ve discussed previously feature tests can become a performance bottleneck for a large test suite. With the fast approaching release of Ecto 2.0, Elixirists will be able to run feature tests for Phoenix applications concurrently. To take

Concurrent Acceptance Testing in Elixir

If you’ve practiced Test-Driven Development, you know that fast-to-execute tests are more than just a nice-to-have. As suites get slow, developers run them less often locally. Failures start to crop up in the CI environment, and the length of time between a breaking change and its detection increases. The problem gets worse with acceptance tests.

Sharing and Testing Code in React with Higher Order Components

Higher Order Components (HoC) in React can be simple to use and test. If you haven’t read about HoC’s and how and why they’ve replaced mixins, check out this great Medium post by Dan Abramov. Most of the resources and examples that I found online about higher order components are complex, and don’t include a

Writing Reliable iOS Tests

Tests help me write better apps. Writing tests informs my interface designs, expresses some of my intentions, and guards against regressions. As applications grow so do the number of tests I’m running as a regular part of my development workflow. If I’m not careful those growing test suites can slow down, become inconsistent, and eventually

Integrating 3rd-Party APIs: Listen to Your Tests

When integrating 3rd-party APIs, it’s important to listen to your tests. The most common design relies on tests that directly mock the 3rd-party API. These tests are brittle, but are often acceptable because, well, they work. A better approach is to take the time to design an app-specific interface to wrap the 3rd-party API. The

Test-Driving the Design of MVC Based Apps

Using tests to drive out the design of objects is an effective way to write code. By taking the perspective of a client, your objects will develop simple, and intuitive interfaces. In addition, the tests act as both documentation and an automated, regression test suite. In this post, we’ll outline a basic test-driven workflow for
