There is high demand for iOS applications these days. iPhones and iPads are gaining popularity with every new release, and so are the apps that come along with them. With so many people demanding iOS apps, the importance of thorough testing has become much more than ever. High standards and good quality are most important for users. With so many apps emerging in the market, one has to maintain really high standards to make it big in the App store.
You need to ensure that your app runs well on all the iOS devices. This is the first thing to keep in mind. You could reach out to a wider audience this way. iPhone App Testing requires a good amount of homework beforehand. Here are some tips to help you in your testing process:
“Untestable Behaviour” cannot exist. There could only be ‘untestable code”. It is a very simple point to remember.
You should be able to test every part of your app. If there is any part that cannot be tested, you must think about refactoring some parts of the code to make it happen. You must have a good answer to the question,” Why can’t I test this?” Your answer could most probably be that the code is either too complicated or there may be too many actions in the code. Resolve such issues by dividing the code and making it cleaner. Make your code more modular, as it helps you to test it more effectively.
You must be very thorough about how your object should behave. It is also important that you have complete confidence in yourself when you say that.
Always attempt to make simple classes that have well defined and concrete responsibilities independent of one another. You must understand these specified responsibilities and should be able to describe them well. There are two important testing frameworks in the world of iOS, Quick for Swift and Specta for Objective C.
Your objects need to know as less as possible. The lesser they know, the lesser you will have to test, and the easier it becomes for you. Remember the rule to minimize adhesion and maximize cohesion. Objects should not be too dependent on each other. Each module must be complete in itself. Your test writing becomes simple if you have less to test in a single module. This ensures a better quality for all your products through effective iOS App Testing.
Over time, there are a lot of changes in the devices, the hardware, architecture, operating systems, and the programming languages. But, there are some classic rules that remain true no matter what changes. They are the solid foundations for building an efficient software product. The S, L, and D rules are essential in the case of iOS App Testing.
According to this, your class must be entrusted with only a single responsibility. This makes it much easier for you to understand its purpose and role in the product. When you understand what exactly it does, it makes it easier for you to write its specification.
You should make sure that your objects can be replaced with other instances. You should be able to substitute objects with instances of their subtypes as well. Mocks are often used to test any specific behaviour exhibited by objects, but such testing could not be applicable for your whole program or system.
Using protocols to decouple your classes is the most effective practice you could use in iOS for testing purposes. Do it for a few parts only and test them independently to assess the behaviour individually. You must test bit by bit as testing it as a whole will never help you.
Your class must never have more than 150 lines of code. If it exceeds the limit, there is definitely something wrong in it. Divide it in to smaller parts that can be easily managed and maintained. This makes your code break up in to smaller units of logical codes. This helps you as well as other who look in to your code. A legible code is an indication of a good developer. It helps you in iPhone App Testing also.
Most developers have the wrong notion about writing tests. They do not help the end user in any way. Moreover, there can be cases where the test case for a class has more lines of code than the class itself. As such, it is considered to be an unnecessary waste of time. But, this is not the case. When you get a code and have no idea what is happening in there, the test cases can actually help you out. There are numerous classes and tricks in every code. Cracking them is not an easy task. When you write tests, it will definitely help in maintenance and testing.
When you are working and get stuck with a piece of code, you tend to overlook other things that matter. Your focus is always put on this single piece that you are working with. You tend to stop seeing other ways to resolve your issues or get your work done. In such cases, you must always take a small break and get your mind cleared. This lets you see the bigger picture at hand. You will be able to find other different ways to get your work done. You could even consult a fellow developer for new ideas to pour out.

Even if you are a pro, you could always learn something new. This is applicable to testing and programming in general. Never keep your mind closed to new things. Most professionals consider their code to be perfect. Even if that is the case, you could always improve. Writing tests will always speed up your development time. Even you break your code unknowingly at times. As such, machine check of the code helps you faster. It is much faster that manually going through every line of your code. So, keep learning and improving yourself for the better every time.
So, here were a few tips you need to keep in mind with regard to iOS App Testing. Some of them are applicable to Android App Testing as well. Building efficient apps that work seamlessly on the intended platform is the ultimate aim of every developer. Follow these steps to make that possible in a more productive and efficient manner.
