7 Software Testing Principles Every Tester Should Know

The primary objective of testers while rendering software testing services is to ensure all system requirements are met. To achieve this, they need to ensure the right strategies and ground rules are followed. This article is to help you understand how software testing principles  will help in testing

For instance, if a file is to be moved from folder A to folder B, many possible scenarios need to be tested like:

 

  • Moving a file while it is still open.
  • If the users have security rights to do an action in folder B.
  • The folder B is operational on a shared drive and it has no remaining storage capacity.
  • There is another file with the same name in folder B.

Here are 7 software testing principles that testers must follow to implement testing with precision:

Avoid Exhaustive Testing:

Optimal testing will require a substantial amount of time and resources. Therefore, testers need to avoid exhaustive testing and go for risk-based testing. It involves assessing the risk based on software complexity, critically of business, frequency of use, possible areas with defect, etc.

Risk-based testing prioritizes testing the more impactful features of the software application that are likely to have flaws. And this type of testing is likely to be implemented in projects that are faced with time, resource, and budget constraints.

Check For Defect Clustering:

Defect clustering refers to a small number of modules containing most of the defects. It means defects are concentrated or centralized across two or three functionalities. This occurrence can be due to the complexity of the application, coding, that is impacting a specific feature.

Checking for defect clusters is crucial as it is found that 80% of the defects are found in 20% of the modules under testing as per Pareto’s law. Seasoned software testers will be aware of what modules need to be checked.

But they also need to be vigilant as running the same test repeatedly on a particular module cannot help find new issues.

Using the Pesticide Paradox:

Pesticide paradox refers to cases where testers need to devise new testing strategies instead of repeating the same ones. When the same tests are performed on specific features repeatedly, it becomes hard to identify new issues. Thus, this technique comes as a timely solution.

Testing More Identifies Defects:

This is an important principle to be followed by every tester as testing more helps identify more defects and also reduces the possibility of escaped defects popping up at a later stage. Leading industry experts are of the opinion that any software can only be 99% defect-free and it can be termed as flawless.

The Absence of Error Concept:

It is entirely possible for testers to not find any errors in an application. Here, they term it as an absence of error where there is no flaw found in the app. Testing of the software for the right requirement is very crucial because the software is designed as per user needs.

If these are not met, even a flawless application might not perform in the required environment. If user needs are not considered, the absence of error judgment might prove to be wrong.

The Principle of Testing Early:

Testing early is believed to be one of the best ways to deliver a flawless software application. Here, both testing and development are done in parallel terms. It helps in discovering issues related to conformity to user requirements and design errors right at the beginning of the process.

Also, fixing bugs later can prove to be more costly in comparison to finding them early and fixing them.

Testing Depends on Context:

Testing of an application depends on the context of how it is to be used. For instance, testing an online tourism platform will be completely different from testing an off-the-shelf commercial platform. Different apps can be tested using different techniques.

It depends on the testing methods that are to be deployed for a specific purpose. In a more practical instance, testing software for an e-commerce platform will diverse requirements compared to testing it for a physical store.

Closing Thoughts:

Merely understanding the software testing principles is not sufficient. These principles are of no use if they are not used at the right time. Experienced testers who are well accustomed to the process can apply these principles naturally.

At Sapizon Technologies, we possess testers who have acquired valuable experience and follow the right principles of the process. It has allowed us to deliver more than 100 successful projects to our clients in this domain. Considered one of the best QA outsourcing companies, we focus mainly on client satisfaction.
