In this article, I’ll share the top 10 lessons I’ve learned after 10 years of software testing.

After spending almost a decade in the software testing industry, I can write about some of my key lessons from years of experience in the software testing field.

People frequently ask whether I will perform any testing in my current role. My answer is, YES, always!

As I have written in many STH posts, software testing is about mind and eyes and not about years of experience. It is expected to grow with experience.

Lessons Picked Up After Years of Testing Careers

Software testing lessons

At a beginner level, when you miss out on a bug, you are just notified about it. At the middle level, when you miss out on a critical bug, you are instructed not to repeat it and at the senior level; you are not supposed to make that kind of mistake.

So with experience, one needs to understand the responsibility they carry. I have just tried to point out my learnings.

#1) Software Testing is Challenging

When I hear that there is nothing to do about software testing, I feel strange.

Isn’t it difficult to taste the recipe prepared by the chef and tell him he forgot to add salt? Isn’t it difficult to suggest the self-proclaimed best painter to use orange instead of blue? Isn’t it difficult to find spelling mistakes in a 200-page book?

That is how software testing is. It challenges you to be alert, well acquainted, and be the one whom people like even if you are finding mistakes in his work.

#2) Software Testing is About Attitude

Always remember that finding faults in other’s work does not give the right to be rude, critical, or authoritative.

The right attitude to help in improving quality should be the prime concern. A tester needs to approach the testing task with the right attitude and should look at the bigger picture rather than just criticizing someone or proving oneself better.

#3) Requires Communication Skills

When your job is to find faults in others’ work and convey the same to the relevant person too, it needs a tactful approach. No one would like to hear “You have made mistakes”, but everyone would respond positively to “We can do this better in this way, don’t you think?”

#4) Demands Analysis Skills

Why do developers willingly resolve bugs, reported by Tester X but not by Tester Y?

Tester X always provides better information about the bug reported. He does some investigation around the issue and tries to understand the root cause of the issue. He will render a bug report with details and that is the reason developers like to prioritize his bugs.

#5) Constant Learning

To survive in any field, one needs to improve continuously and software testing is also not an exception either.

The market is flooded with a variety of tools, documents, blogs, and many other means to learn new things. To grow and be good at what you are doing, you need to select the one based on your area of work and choices, along with current demands.

For example, five years ago, has anyone ever thought that we would look for mobile testers so badly? That’s how technology, generation, and demands have changed and, to survive, and learn.

#6) Does Not Ask For Certification but Skill

There is nothing wrong with getting certified, but it’s not compulsory.

A good tester needs to possess testing skills like a sharp eye for detail, analytical and troubleshooting skills, etc. and I believe no certification can prove that you are good at those mentioned skills. While writing test cases, none of us would prefer to think about boundary value analysis and decision tables specifically. What one needs is the application of common sense on knowledge.

#7) Self-motivation

Who would like a person who shows litter on your balcony and makes you sweep it? No matter if he is helping to make something clean, mostly he won’t be appreciated.

That is how the profession is! You might or might not be appreciated for the quality work you are doing but you need to understand the importance of what you are doing. And timely, you need to pat on your back for the work you are doing.

Tell yourself “I am doing the best job in the world as I am helping in improving something”, at day start and you will need no one’s favorable judgment to motivate you.

#8) Understanding Priority

What will you choose when you want to attend a party but you have to be at home to look after something? You will understand the circumstances, will decide on priorities, and will select the best option.

This is how software testing too works. As a tester, many tasks can distract you at a time, but you need to understand the priority of each, learn from past experiences, seek advice from those who have already experienced it and ultimately work as per priority.

When you are in a crunch of time, there is no need to document everything but to perform testing and likewise, all processes need to be followed for a maintenance project.

#9) Customer Satisfaction in Qualitative Ways

If you are a tester, you need to be an end user.

It does not matter how the product should be used, but it matters to know how the product can be used because that is how the end user is going to use the product. It will be helpful to put yourself in the end user’s shoes and think about the behavior of the product when not closed properly, tabbed continuously when handled by a child, or when there is no power, and so on.

In the real world, how many of us start our computers according to the user manual? Most of us don’t. Because for us, it’s a process we have become familiar with over the years and now we feel that no documentation can enhance the process.

The same applies to the end user’s expectations, too. Everyone simplistically wants a superb product and as a tester, your job is to test that simplicity.

#10) Job you can be Proud of

I don’t think I need to write a single word about this point. No one can make you feel inferior without your consent. And remember, if you’re not proud, you’re not done.

Conclusion

Be smart, follow your heart and your goals. I’m sure you will find yourself on a career path that fills you with confidence and pride. I hope you can learn something from my experience and grow at a much faster pace in your career!

  11. Some things you missed out are like:
    1. Be a suck up to managers
    2. If the client tells you to stop testing, you put all the defects up your rear.
    3. Testing has become a joke in most corporates
    4. Testers are looked upon as though they have no skill
    5. During layoffs, testers are targetted more.

  13. Thanks STH team…you are doing a wonderful job.
    Love all the articles that you publish.
    Recently you have published a course for beginers/freshers/laterals who want to take up testing as a career option. But the timings are not really comfortable… can the same class be opted from 8pm to 10pm…. that would be comfortable for people who are working and looking at other options….

    Waiting for a positive response.

    Thanks in advance.

  16. Excellent post Bhumika..! Very inspiring ..! 🙂 Every lesson what you have mentioned is very true. Its really very annoying to listen from developer’s that, we testers doesn’t work hard like them or when they say.. Testing is a very easy job, which can be done by anybody. The most annoying is when a developer behaves rudely, when we log a bug. In all the above situations we, really need patience to work in such an environment. This post will really motivates us and make us proud for our challenging work. 🙂
