Mozisha: 10 Common Mistakes Made by Software Testers and How to Avoid Them

Software testing is not an easy job. It involves a lot of thinking and problem-solving. The software tester needs to understand the user requirements thoroughly and identify if the software meets those requirements or not. If there are any bugs in the software, they need to be identified and documented properly. This is so that they can be fixed by the developers.

Here’s our list of 10 pitfalls that commonly trip up testers, along with what you can do about them:

Lack of Stakeholder Communication

Stakeholders are very important in the software development lifecycle. As a software tester, it is important to communicate effectively with the stakeholders of the product. If there is a lack of communication, the testers will not have a proper understanding of the product requirements. This will create a situation wherein the testers will not be able to execute their job correctly.

The job of a software tester is to test the product and identify if it meets the requirements set by the stakeholders. Before testing the product, they should have a proper understanding of what is required and know where to look for issues.

Communication is not about talking only; it’s about listening, too. Software testers are to ensure they have an understanding of everything the stakeholders say and ask for clarifications when required. With good communication, the testers will be able to understand the requirements and will be able to do their job better.

Assessing Risk Incorrectly

When assessing risk, software testers need to be able to identify the chance of a particular issue occurring, the impact if it does occur, and the effort required to mitigate that risk. Risk can be incorrectly assessed for many reasons.

Despite the appearance, it’s important to remember that risk has nothing to do with severity. One of the most common issues is that testers focus on how severe an issue is (how many customers will be affected, etc.) and completely ignore how likely that issue is to happen.

Furthermore, when recording risks, it’s important to remember that not all risks should be recorded. Only record risks that are likely to happen or that have a measurable impact if they do happen.

Having a Bloated Test Suite

Test cases are a necessary part of the software testing process. They let you know what you are to test and how/where to test it. There might be a situation wherein the test suite is too big.

A test suite that has too many test cases can be very confusing for testers and can cause them to lose focus. When this happens, they might not be able to execute all the test cases properly. This can lead to incomplete test cases and a lack of thorough testing.

When you have too many test cases in your test suite, you can either merge the test cases or mark some of them as not applicable to the current build.

Not Enough Testing Time

Software testing should start early in the software development lifecycle. Involve software testers from the beginning. When a company hires software testers, they expect them to do a thorough job. This means they will have to spend enough time testing the product. If the testers are under pressure to finish the job in a flash and don’t have enough time to test the product properly, there is a possibility that they might miss some important issues and create incorrect or misleading reports.

Involving testers early in the project can, among other things…improve quality, save time and help ensure the best possible user experience.

With enough time (and resources) to thoroughly test the product, testers will produce reliable and accurate reports.

Focusing on the Wrong Thing

As a tester, you have a lot of responsibilities. You need to understand the application, the user requirements, the business objectives, the testing methodologies being used, and more. You also need to be able to identify which issues are critical and which ones are not. It’s important to remember that not all bugs are created equal.

To ensure that you’re focusing on the right things do these:

  1. Identify which issues are critical and which ones are not.
  2. Only report critical issues. Report all non-critical issues but don’t spend as much time on them.

Incorrect Positioning in the Development Team

The quality of the product depends on the software testers and the development team working together. If there is miscommunication or a lack of collaboration between the development team and testers, the product will not be of good quality. This can be avoided if the testers and the development team work together and share their knowledge and expertise. If the testers are not collaborating with the development team, they will have a limited view of the product and will not be able to test the product thoroughly.

No Test Automation Strategy

There are two types of testing: manual and automated. Manual testing is done by human beings and automated testing is done by software. Automated testing is done by creating test scripts using various QA tools. This helps save time and lets the testers execute the testing task more precisely. Yet, there is no strategy applied to automate the testing, which can lead to incomplete testing. Manual and automated testing are two parts of the same process. Manual testers should also write automation scripts so that they can create a successful automation strategy.

Existing Quality Control Tools Are Not Used or Understood By Testers

There are several quality control tools available in the market. Some of them are used by the developers while some are used by the testers. If testers don’t understand the importance of these tools or how to use them, they might not be able to find issues in the product that could be easily identified using these tools. This can lead to incorrect testing and inaccurate reporting.

Assuming Everything Works Until Proven Otherwise

This is a big one because it’s an easy trap to fall into. Assuming that everything works the way it’s meant to until proven otherwise is a good way to miss critical bugs and issues. It’s an easy trap to fall into because it’s natural to assume that everything is working as it’s supposed to until proven otherwise. However, it’s important to remember that this is the software testing equivalent to closing your eyes while driving. It’s important to make sure that you’re testing everything properly so that you don’t miss anything.

Outdated or Non-required Documentation

Requirement documentation is the most important part of the software testing lifecycle. They let you know what to test and where to test it. If there is no requirement documentation available, the testers will not know what to test and how to test it. This can lead to incomplete testing and inaccurate reporting. If the required documentation is outdated, it can cause confusion among testers and they might not be able to understand what they are supposed to test.

Summing Up

Software testing is a complex job. Not only do you need to be a whiz at identifying bugs and errors in code, but you also need to understand the functionality of the software perfectly so that you know exactly where to look for issues. It can be a stressful job, but it doesn’t have to be if you follow these 10 tips on how to avoid common mistakes made by software testers and how to avoid them.
