Website bugs reduce revenue, increase bounce rates and negatively affect the overall performance and usability of a system. Bugs occur every day, as new functionalities are launched, products are uploaded and a website or app continually evolves to match changing customer expectations. For internal teams that focus on the performance of a website, these bugs create hundreds of problems and take up huge amounts of time, which should be spent developing new products.
One of the prime ways companies reduce the likelihood of these bugs from being created is through functional testing. Simply put, functional testing validates an applications standards against a set amount of requirements.
When functional testing, a testing professionals main goal is to validate the application to ensure quality. They do this by pointing out areas which have issues or are simply ‘not right‘. This type of website testing is extremely important in the digital world, but it can take 2-3 weeks to complete as internal teams struggle through their extensive list of tasks.
Here are 5 top ways you can speed up bug identification through functional testing:
- Know your purpose
Even before you begin testing, your teams should be asking themselves Why? and What?
Why are they testing? And what requirements does this system have to meet? Once your teams have a clear idea which is noted down, understanding exactly how a system should behave will make the whole testing process easier. This first step sounds pretty obvious but you would be surprised how many internal teams simply go on what they think is right, instead of what has been outlined.
A tester should understand each and every feature of the application, its use, the way it is implemented etc. For every functional tester, this is the first place to start identifying defects. One of the quick ways to understand the application and its features is through functional exploratory testing. This way, a tester can explore and also learn simultaneously.
2. Know your integration points
A website or app is usually comprised of several components, out of which, many communicate with different interfaces. Be it an API to search some criteria/ an interface which sends or receives data from another component/ a query which connects and retrieves data from the database. These integration points can be the main sources of wrong outcomes and unexpected results.
Sometimes, the integration components and the data transfer can be simple and the components can be even the modules of the application. And, sometimes, they can be complex. Understanding these components and planning the test scenarios for an end to end flow will help in finding valid defects.
3. Negative scenarios and alternate paths
Sometimes, understanding the requirements is not enough to find valid defects. There might be some negative scenarios/ alternate paths that might not have been covered in the requirements.
Testers should always think “out of the box” and imagine the actions a user might perform. It is not only important that the application should work as expected but also, that it shouldn’t behave in an abnormal way.
4. Perform Use case and Scenario-based testing
Testers should understand the user flow and build test scenarios based on them. A tester should understand and draft the flow and try to test with the test data which is nearer to the production data to identify the problems in the application. Ensuring you have all of the steps documented and catalogued will make the testing process easier in the future and provides evidence of the work performed.
5. Exploratory Testing
This last tip always works for our professional expert testers, whenever they think they can’t find any more defects.
From our community – “When we test all features with a specific time set for each, focusing only on finding defects, we can find more valid defects in less time. A tester can make a list of all features/modules/functionalities, set time for each item and cover both positive and negative scenarios. All CRUD (Create, Read, Update and Delete) operations on all fields, UI and Usability tests, verifying the correctness of data of all fields and the user flow can be the main focus points in timebound testing.”
The success of finding more valid defects in less time depends on the skill and the experience of your internal teams/testers. Domain knowledge, understanding the long-term vision and the purpose of the application is very important for any tester, and an expert tester will have already highlighted these steps. Luckily our community of testers are experts in their field and if you want to improve or even begin testing, we can help every step of the way.
Website testing should always be an adaptive and intuitive process, where we can update the test strategy as per the behaviour of the application. All the above tips which are based on the same point will definitely bring success to testers in improving the quality.
