testing

Modules are super useful for splitting our projects into smaller, more manageable parts. But they could be doing more. Here, we look at how a utility module can ease the burden not only for production targets but also for test targets.

Core Data and Unit Testing haven't always been the best of friends ⚔️. Core Data is all about persisting. Unit testing is all about forgetting. Here, we look at how they can work together with the help of UIKit to ensure that we gain the confidence we need to ship an app.

An uncomfortable truth is that praising firefighting developers might just be leading to more fires. Here, we look at why needing firefighting developers is a sign that your processes need to be improved, as avoiding fires is better than managing fires.

We want to test that our network stacks can make network requests as intended but without actually making those requests. Here, we look at how to split our networking stack into components to allow easy unit testing.

No one said running your unit tests on Travis CI would be easy. Who knew running tests via the Xcode UI wasn't the same as running those tests via the terminal 🤷‍♂️? Here, we look at how to prepare your test targets for running on Travis CI.

View controller accumalate stuff. If you are not careful you can turn in a view controller into a hoarder's den. Here, we look at how to extract functionality from a view controller and rehome it using Single-Responsibility Princple.

Everywhere you look, you are being told to write unit tests, but what even are unit tests? Here, we look at what testing is, why you need them, who should write them and when to write them. And ulitmately how unit tests allow you to go faster.

A lot of developers rely on intuition to identify the test cases that exist in their apps. This approach leads to inconsistent coverage, missed edge cases and bugs. Here, we look at how to ditch the intuition approach and get systematic in our identification of test cases.

Testing isn’t one hurdle but a series of lenses - unit, integration, system, and acceptance. Each reveals different truths and mitigates unique risks. Together, they form an ecosystem of trust that helps teams ship with confidence. Here, we look at that ecosystem.

You are a great developer, so why go through the hassle of writing unit tests? Here, we look at the reasons beyond writing unit tests and how to win over a unit test sceptic

Dependency injection is one of the superpowers that developers can utilise to produce code that is more predictable and easier to test. Here, we look at dependency injection - what it is and how we can utilise it.

Oversharing is bad. Social media taught us this. But so did '101 Introduction to Object Oriented Programming'. Here, we look at how to avoid oversharing by designing our types to be defensive.

Boundary Value Analysis and Equivalence Partitioning are essential tools in any QA's toolbox when designing testcases. Here, we look at what they are and how to use.
