The contemporary world as it exists cannot run without digital devices and software. Computer software plays an integral role in the functioning of every digital device running this digital era. Therefore, software development becomes integral to any sector of the world economy. However, software development always includes software testing, an aspect that not everyone knows or appreciates. So what does it entail? What best practices get involved in software testing?
Software Testing Best Practices
Quality assurance proves pivotal in software development at the moment, and it will continue as more people become tech-savvy and the world continues to rely on computers to function. If you doubted the importance of quality assurance in software development, you should think again. Plenty of research and the latest security breaches serve as an ideal reminder. Additionally, the overreliance on computers due to work-at-home measures has increased the likelihood of cyber-related attacks. Therefore, software testing and quality assurance become instrumental in identifying the causes of these vulnerabilities and rooting them before the software reaches the production stage.
To understand this subject better, consider the following software testing best practices checklist.
- Invest heavily in the secure testing setting
Advances in tech have ensured the emergence of the cloud as an ideal work and storage space. However, as much as this space proves ideal for collaborative work and communication, it proves unsuitable for testing and developing software. Software developers require a secure and local setting to perform software testing, the same way medical scientists rely on secure and clean laboratories for doing experiments. Therefore for developers, their environment needs to prove devoid of the internet.
- Test throughout
It becomes essential to test the software full-circle as it gets developed because it always reduces the burden when doing quality assurance. While some individuals might think testing has to happen after development, regularly testing through development helps limit errors as you progress. But if you leave everything up to the quality assurance stage, then you will exert plenty of pressure and burden on your staff, which will reduce your software’s quality.
- Perform smaller tests
It becomes pivotal to do smaller tests as you perform the stage-wise tests. Deconstructing will limit resource and budget overloads, which often prove typical jeopardies.
- Adopt negative testing
While positive testing determines whether an app can handle its expected objectives, you must embrace the opposite, negative testing. It will increase the robustness of an application and contains fewer faults than testing and allowing software to operate under standard conditions.
- Perform regression testing
It so often happens that when you persistently modify a code to fix a single problem, you easily end up creating another. However, one best practice entails using reusable regression testing, especially in agile development. It will ensure that the specific code added to remedy a problem avoids causing another. Additionally, it becomes crucial to segregate the test cases besides graphing the bugs to increase effectiveness. In this manner, you can easily spot problem spots.
- Write test prior and avoid letting programmers do it for you
It also gets referred to as the test-driven development. It has various benefits, including saving time by correcting faults before writing or running a new code. Moreover, it bypasses duplication of code which eats o your time. To become safe, avoid letting programmers write tests when it involves their code as it can introduce bias, which impedes progress. It also proves devoid of creativity and thus makes it tough to challenge the code to improve it.
- Document observations
It matters very little whether the tests prove automated or manual, as you have to take notes from every observation to eliminate ambiguity. It also offers excellent training material and a firm foundation for configuration manuals and documents.
- Clean your code
Cleaning code in the code testing phase implies housekeeping activities to ensure everything is in order. For instance, you can make a code concise to make it easy for another software developer to use it for testing. Additionally, code simplicity ensures easier testing.
- Test in an environment devoid of designers and developers
MVC facilitates collaboration among designers and developers, which leads to frequent changes. Testing an app in such an environment proves challenging, and therefore, when you take it out of this setting for a while, you can reduce potential confusion besides making the process complete.
- Develop a TOM (Target Operating Model)
It entails a malleable framework that offers developers ways of running their workflows besides tracking their progress. Therefore, a prior definition of the methods, processes, and tools ensures that the goals become clear to every team member, which unifies the team. It also assists new members of the team in integrating and comprehend product objectives.
- Separate performance and security
Performance testing and application security require two separate and different skills. While the two are related, security testing entails vulnerabilities and loopholes that entail ethical hacking and simulation of attacks. On the other hand, testing performance entails benchmarking app behavior. To separate the two teams would imply avoiding the dilution of each member’s specialization besides keeping everyone sharp.
- Communicate with end-users
To provide your project with a better context, it becomes crucial to get some time and meet end-users. You will understand their issues and some of the features you have to improve to boost productivity. Additionally, it matters very little, whether external or internal, but talking with end-users proves an excellent idea.
- Prioritize tackling essential code changes
To fix bugs, concentrate on the aspects that link heavily with end-users. Thus, it becomes crucial to pay attention to these code changes the most.
- Influence sanity testing
The process entails a thorough procedure that aims at more tropical software attributes. It acts as a perfect foil whenever you do not have sufficient time to perform full regression testing. The sanity testing will ensure everything works as you have anticipated, and this makes it ideal for fixing minor bugs. While it may seem shallow for some people, the exercise aims to save time with minimum effort. Additionally, to make it more effective, use a two-tier strategy that allows you to run a rapid sanity check and provides developers with immediate feedback. You can then run your deep automated regression testing at night to get a better context.
- Use outsourced and in-house teams as well
Assembling an all-in-house tester team often proves an arduous task and often impossible as it takes away a specific level of investment infrastructure that plenty of people cannot make. But for budgeting’s sake, companies have to rely on outsourced quality assurance teams. Therefore, you have to compromise between the two and use both outsourced and in-house teams to get excellent results. It will give you a rich blend of expertise and experience to help you comprehend the consumer market.
- Realize better control complete with component-based architecture
It becomes a different scenario when faced with multiple stakeholders possessing diverse expectations besides divergent outlooks on the project. The perfect method of managing this entails taking component-based architecture. It dissects the end-product into functional and logical components and allows project managers to isolate diverse dependencies better. Additionally, it supports component reusability.
- Embrace different testing strategies
The diversity when it comes to the testing strategy assists you to quickly spot diverse types of bugs, which can cause headaches further along.
