ii. About the Tutorial. Testing is the process of evaluating a system or its component(s) with the intent to find whether it This tutorial will give you a basic understanding on software testing, its types, methods, levels, and .. Manual Testing. This chapter describes the basic definition and concepts of Testing from Software point of view. .. Manual testing also includes exploratory testing as testers. Manual Testing Tutorial - In this manual testing tutorial, we have covered all important topics in simple and Manual Testing Tutorial – Table of Content | Software Testing Material . End to end Manual testing details in Video & PDF Format.

It describes how each and every feature in the product should work and how every component should work. Here, only the design will be there and not the code. For ex, let us consider the example of building a house. Testing :- done by test engineers - it is the process of checking for all defects and rectifying it. For ex, consider the example of a software to be developed and installed at Reliance petrol bunk. Maintenance :- here as the customer uses the product, he finds certain bugs and defects and sends the product back for error correction and bug fixing. Service based companies and Product based companies Service based companies : They provide service and develop software for other companies They provide software which is and specified as per the client companys requirement and never keep the code of the developed product and does not provide the software to any other company other than the client company.

It has a very narrow focus and is performed by the test engineers in parallel with the development process or at the dedicated testing stage depending on the methodological approach to the software development cycle.

Namely, it is used to make sure that every single action is performed in the right order, every detail is properly implemented and the overall processes are consistent so that nothing can cause a negative impact on the end product. Quality control can be compared to having a senior manager walk into a production department and pick a random car for an examination and test drive.

Testing activities, in this case, refer to the process of checking every joint, every mechanism separately, as well as the whole product, whether manually or automatically, conducting crash tests, performance tests, and actual or simulated test drives. Due to its hands-on approach, software testing activities remain a subject of heated discussion.

That is why we will focus primarily on this aspect of software quality management in this paper. The Main Principles of Software Testing Formulated over the past 40 years, the seven principles of software testing represent the ground rules for the process.

These are: Testing shows presence of mistakes. Testing is aimed at detecting the defects within a piece of software. But no matter how thoroughly the product is tested, we can never be percent sure that there are no defects. We can only use testing to reduce the number of unfound issues. Exhaustive testing is impossible. There is no way to test all combinations of data inputs, scenarios, and preconditions within an application.

For example, if a single app screen contains 10 input fields with 3 possible value options each, this means to cover all possible combinations, test engineers would need to create 59, test scenarios. In order not to spend weeks creating millions of such less possible scenarios, it is better to focus on potentially more significant ones.

Early testing. As mentioned above, the cost of an error grows exponentially throughout the stages of the SDLC. Therefore it is important to start testing the software as soon as possible so that the detected issues are resolved and do not snowball. Defect clustering. This principle is often referred to as an application of the Pareto principle to software testing.

This means that approximately 80 percent of all errors are usually found in only 20 percent of the system modules. Therefore, if a defect is found in a particular module of a software program, the chances are there might be other defects. That is why it makes sense to test that area of the product thoroughly.

Pesticide paradox. As soon as the detected errors are fixed, these test scenarios become useless. Therefore, it is important to review and update the tests regularly in order to adapt and potentially find more errors. Testing is context dependent.

Depending on their purpose or industry, different applications should be tested differently. While safety could be of primary importance for a fintech product, it is less important for a corporate website.

The latter, in its turn, puts an emphasis on usability and speed. Absence-of-errors fallacy. The complete absence of errors in your product does not necessarily mean its success. While the above-listed principles are undisputed guidelines for every software testing professional, there are more aspects to consider. Some sources note other principles in addition to the basic ones: Testing must be an independent process handled by unbiased professionals.

Test for invalid and unexpected input values as well as valid and expected ones. Testing should be performed only on a static piece of software no changes should be made in the process of testing. Use exhaustive and comprehensive documentation to define the expected test results.

Waterfall Model Representing a traditional software development life cycle, the Waterfall model includes 6 consecutive phases: planning, analysis, design, implementation, testing, and maintenance. SDLC Waterfall Model In the testing phase a product, already designed and coded, is being thoroughly tested before the release. However, the practice shows that software errors and defects detected at this stage might be too expensive to fix, as the cost of an error tends to increase throughout the software development process.

However, the damage grows exponentially throughout the further stages of the process. If such an error is detected at the design stage, you will need to rework your designs to fix it.

This will require a significant amount of effort and investment. The same is the case for errors produced in the process of implementation.

If a feature has a flaw in its logic, building more functionality on top of it might cause a serious damage in the long run. Therefore, it is better to test every feature while the product is still being built.

I will try to help you out in this. I highly recommend you to go through this before continuing with the tutorial. It will, in turn, help you to compare your qualities against the ones that are expected in the Software Tester's role. It worked for me and I strongly believe that it will work for You as well.

If you have these qualities already, then indeed it got to work for you too. Now let's understand why it has and would always have its independent existence with or without Automation testing growth. You yourself have to work on it. You will have to develop the habit of asking questions and you will have to ask them every minute when you are testing. Most of the times you should be asking these questions to yourself than to others.

I hope that you would have gone through the article that I recommended in the previous section i. If yes, then it will give you much clarity on how testing is considered as a thought process and how successful you will be as a tester completely depends on the qualities that you possess as a person.

Then Your observation skills and discipline to perform things comes into the picture here. What was that? You noticed something. You noticed it because you were giving perfect attention to the details in front of you. But now you are doing it. You are happy, you found out the cause, the steps, and the scenario. Now you will communicate this very properly and constructively to the development team and the other stakeholders in your team.

You might do it via some defect tracking tool or verbally, but you got to make sure that you are communicating it constructively. What if I do it that way? What if I enter proper integer as input but with leading white spaces? What if? The Diagram given below represents the Life of a Tester: Read those four bullet points mentioned above once again.

Did you notice that I kept it very short but still highlighted the richest part of being a manual tester? And did you noticed the bold highlighting over few words? Those are precisely the most important qualities that a manual tester needs. Now, do you really think that these acts can be completely replaced by anything else? And the hot trend today, will it get replaced with automation? In Software Testing Life Cycle with any development methodology, few things always remain constant.

You will then execute those test cases or directly automate them I know few companies do it. When you automate it, your focus is steady, that is automating the steps written.

Here, you not only focus on executing the written test cases, but you also perform a lot of exploratory testing while doing so. Remember, you are curious? And you will imagine. The image given below depicts how Test Case writing is simplified: I am filling up a form, and I'm done with filling the first field.

I am too lazy to go for the mouse to shift focus to the next field.

I am done with filling up the next and last field too, now I need to click on Submit button, the focus is still on the last field. Let me check what happened. OR there is a submit button, I am gonna double click it. Not satisfied. I click it multiple times, too fast. Did you notice? There are so many possible user actions, both intended and non-intended ones.
