Usually, testers are responsible for identifying all the mess that developers create in a system. No matter how experienced the developers are or how much effort they put into, there is little chance of creating software that is completely error-free. Although it is equipped with a rich toolbox including test case management software, software test tools, test automation applications, etc., it always becomes difficult for testers to identify all the problems at once. Testers need to develop a thorough understanding of the software, its environment, and have a nose to smell bugs and identify them using different tricks and techniques. The job of a tester is not just limited to identifying the issues only, they should also communicate them to the respective people and then check whether these issues are resolved in a timely manner or not.

If errors are identified by end users rather than testers, the situation can get worse and frustrating. Again, at this point testers are to be blamed for how they let these flaws slip while running the tests. Testers spend hundreds of hours going through thousands of line code to ensure the end product will perform as required.

What makes testing difficult?

Many factors are observed during testing and all of these aspects should be considered with vigilance. Below are mentioned some reasons which explain the technicality of the said work.

  • To effectively test software, not only do you check it against the correct entries, but you must also record its response against the incorrect entries. With this, all kinds of performance and functionality parameters are checked throughout the testing process, which itself is a time consuming process.
  • The testing process should be recorded so that there is evidence that testing is performed with all test cases and that transparency can be maintained.
  • A system should be tested through different perspectives. First, you need to make sure that all the listed requirements are exceptionally fulfilled, and then you need to consider the user’s perspective to verify the testing process.
  • There are programs and software that get complex with development and at some point it becomes difficult to test all of their requirements. You need to create real case scenarios and test the application.
  • The load and performance of the application should be tested and how it acts when stress is placed on the application. This aspect is really important and takes time. Testing an application against a real-world environment is crucial and approaches must be identified to ensure system security.

Testers and the testing processes they follow

Before starting the testing process, testers should fully understand the software and consider all of the features against which the tests should be performed. The inputs and the environment are meticulously considered for which the whole testing strategy would be designed. This entire process is time consuming and requires a good understanding of the technical aspects and the tools that can be integrated to create the entire test flow.

The work of testers includes expertise with test case management software, automation tools, bug tracking tools, and the creation of policies and processes through which consistent testing practice can be expected. They must ensure that no areas are tested and that all the requirements that were discussed in the initial phase are met. Usually, testers are not given due respect for their work and they have to document all processes so that they have something to present at the end of the day to promote transparent accountability.

No matter how simple or how complex the software, there are different obstacles that must be encountered. The tests go through different phases and are carried out in several parts so that all the defined requirements are met. The four phases during which the tests are carried out are:

  • Realization of test cases
  • Evaluation of test cases
  • Modeling of the software environment
  • Measure software progress

These phases help build the structure of the test and ensure that you are going in the right direction. Testers must come up with a strategy through which the interaction between the software and the environment can be constructed and different interfaces can be identified. Testability is the structured way in which one can understand the complexity of a program and highlight any areas that may affect quality in any way. If one tends to skip the testing phase then they are probably making the most costly mistake and will certainly regret it in the future.
