Test Case Review-Manual and Software Testing

Testing implies executing or running a software program to find the errors using a test case review. To further simplify the meaning of this process, imagine a computer program is written with the help of a team, now there will be chances of errors in this program, which unless resolved will not give the desired output. To resolve these errors, the software firms use the ‘test-case review’ process to find the bugs or errors in the program.

We now have an understanding of the testing process but what exactly is the test case review?

Test-Case Review:

This process involves a testing team whose primary objective is to eliminate all the issues in the code and changes to attain a perfect program.

A team of engineers is assigned to this process and handed over with individual targets. The presence of a testing team ensures that all the minor bugs are resolved, allowing for a smoother run of the given program. Test case review can be termed as the building blocks of a testing process and helps us oversee the entire testing process. This segment ensures perfect testing of a program. All the issues encountered while testing can be solved easily, increasing efficiency.

The flow chart for a Test Case review

  • The testing time is assigned the test of preparing the necessary test cases.
  • A reviewer is assigned to the team to check the presented segments and their alignment with the given task
  • This is saved as the ‘review document
  • The Test lead then reviews the given document and on his approval, this file is sent as the test case repository.

Test-Case Repository:

This is basically the storage location of all the test cases in a simplified manner for reviewing the files at any given instance.

Test-Case Review forms the framework of the testing process.

Software Testing:

Software testing is a basically a technique where a given program/code is verified and validated to ensure that there are no bugs found after compilation. The testing also oversees that the given code meets all the technical requirements including the exceptional cases as well.

The technique is not only restricted to finding the bugs in the program but it also works on improving the accuracy and usability of the program.
It can be briefly classified as:

  • Manual testing
  • Automated testing

Manual Testing:

Manual testing is a method, where human testers are assigned for checking the errors in a given program. The term manual means no automation. The fundamental principle of manual testing involves a group of testers assigned to a written code by the development team. These testers prepare a set of test case reviews individually looking for errors in the given program.

The testing process goes hand in hand with the development team. Work is done in tandem to ensure that the code has no errors or bugs when run in a compiler and that the code satisfies the requirement. The involvement of human testers ensures that it has an edge over the automated testing process.

Flow-chart of manual testing process

Requirement analysis:

The primary objective in a testing process is to always have a clear understanding of the requirement. Once the development team has presented a beta version of the code which needs fine-tuning, the testing team is handed over the code with a given set of instructions regarding the objectives to be attained with the help of the given program.

We can simplify this with help of example;

Let us assume a software firm being handed the task of developing an application for retail store. The development team has presented a beta version of the application, now the testing team is assigned with the responsibility to detect all the bugs or errors in the given code which goes in hand with the requirements of the client.

Test Plan Creation:

The testing team is assigned with the beta version of the code. They now design a route-map on detecting the bugs and solving them to ensure an error free code while following the basic requirements given. The test lead has on overview at the given task and assigns individuals of the team with segments from the code which are to be resolved.

Once the individual testers have done their respective tasks, the lead oversees all the segments and if they are error free as expected then he sends the code for final approval.

Test Case Creation and Execution:

The individuals in a testing team are assigned with particular segments of the given code. Here they work on creating ‘test case review’ for having a thorough scan of the program at hand.

The process basically involves solving all the bugs/defects at hand by breaking the code into small segments or test cases. Since the segmentation of the program has been done, this allows the testers to have a clear understanding of the program, having an efficient output at hand. Once all the test cases have been reviewed by all the team members thoroughly , they are sent to the team lead for a review.

The execution part is done by the team lead wherein he/she has on overview of the entire program at hand. Once the all the test cases are reviewed by the lead, he executes it to check for any bug presence. If any bugs are found in the given test cases, then they are sent back to the team again for solving them at the earliest possible and sent for review. If the presented segments have no errors, then the lead approves it and sends it back to the development team to check whether the code is able to serve all its primary and secondary functions.

Manual Testing as a process has been in use for a long time and it has several advantages.

Some of these advantages are listed below:

  • Since the entire testing process has been done by a team, it has a human touch to it. The testing team being experienced has a clear idea on how to approach different scenarios and provide efficient solutions with the help of ‘test case review’. The analytical and problem solving ability of the human mind has always an edge. This ensures that the firm can rely on this technique for bug detection and solving.
  • Since the entire process is done by the testing team, there is no cost of automation to the firm. It is equally important to ensure that cost cutting is done at every possible instance. A manual testing team would mean that there is no need to purchase automated testing software which almost does the same task, thereby reducing the additional cost to the firm, which can be utilized at some other place.
  • Automated testing cannot be used in every situation. There are some particular situations which demand for the presence of a manual testing team. One of the primary reasons being the edge of having the analytical and creative human mind which always takes an edge over the software.

Irrespective of all the above mentioned advantages manual testing still has its own share of disadvantages , which primarily include the efficiency issue.

For example: Assume that the development team has presented its rudimentary code which has bugs to be resolved. Now if we simultaneously assign manual and automated testing techniques, the efficiency of the automated testing would be higher than the manual testing. The time taken by the automated testing would be comparatively on the lower side.

Examples where manual testing would be beneficial are:

  1. Adhoc Testing– This one of the testing scenarios where there is no properly devised plan for testing. A manual testing team would shine in such an occasion because they are efficient in taking on the spot decisions. Limited time and lower cost of the project would also be one of the reasons in this case where manual developers would be really efficient.
  2. Exploratory testing: It is a form of Adhoc testing which involves exploration of new features which can be used in the already existing program or finding bugs which were missed in the earlier iterations. In order to achieve this objective, creative skills are necessary to ensure which kind of features can be taken into consideration for improving the efficiency of the program and also enhance the user experience.

The aforementioned advantages and examples of manual testing shows its relevance in the current scenario but to keep with the fast paced changes in the digital world, it is important to understand the importance of using automated testing and unlocking it to its true potential for extracting the best possible result.
Let’s have a quick view at Automated testing.

Automated Testing:

Automated testing can be determined as the usage of software tools to entirely automate the testing process i.e. reviewing and validating the process. The process basically involves the automation of the human driven process of the testing.

Most of the Agile and DevOps projects implement automated testing techniques. Since the majority of the testing process has been automated, this has several benefits to the testing team, some of the major benefits being:

  • Leaner team size: The automation of the testing process has ensured that majority of the manual functions are easily carried out by the software ensuring that the team size is reduced. A small team would be directly ensuring that the entire process is being much more efficient and lesser time being consumed.
  • Focus on essential features: Since all the basic tasks of a testing process are being done by software tools, the testing team can now allot their entire focus to the sensitive features of the program.
  • Accuracy: Since the entire testing process is automated, the chances of manual errors is eliminated completely thereby ensuring an efficient product.
  • Parallel Testing: The usage of software tools for the testing process ensures that multiple sets of codes can be reviewed simultaneously without disturbing the other set of codes. To simplify this, let us take an example;

A testing team is currently working on 5 assignments and all of the deadlines are nearby. Even with the efforts of the entire team, they are convinced that they cannot deliver the reviewed documents in the given deadline. In this case usage of software tools for testing, i.e. Automated testing enables the team to work on all the codes in parallel reducing the overall time taken, making it an automatic and efficient choice for future uses as well.

  • Increase in the coverage area: With the help of automation in testing process, we can expand the coverage area of the given assignment. It means that, through this mechanism, we can have a look at every single statement in the given code, having a thorough check of the working, detecting all the encountered defects/bugs in the program. In certain exceptional cases when the code is too complex and certain testing processes are restricted when done with the help of manual testing, this has a direct impact on the overall efficiency of the program at hand and users will definitely experience difficulties while using such programs. Automated testing ensures that such difficulties are not encountered and all the bugs in the program are detected at the earliest possible stage to have a smoother running of the program.
  • Reusability: One of the most important and useful feature of the automated testing process is that, a thoroughly reviewed program already in application can be modified with certain changes to enhance its functioning.

For example: An application has been developed and tested with the help of automated testing program , eliminating all the possible bugs and elevating its performance. Now with the help of this testing program, we can make slight modifications in the given program to ensure that the functioning of the program is further enhanced and also eradicating possible bugs which might be encountered after applying these new changes. Since the process is entirely automated, manual efforts are not necessary, which means that the time of the testing team is saved and they can focus their creative skills in some other program which needs the manual handling.

The advantages of this testing program being diverse have ensured that majority of the firms right now are interested in using this over the traditional manual testing method. The primary reason for this change can be accounted to the fact that the improved efficiency and the above listed advantages have in turn increased the return of investment to the firm and reduced the costing.

Conclusion

To make a conclusion, the highly efficient automated testing can be implemented over the traditional method owing to its advantages which enable it in taking a clear head start but one must be aware of the fact that there are still places where manual testing has a clear hold and one must not discard its existence due to the emergence of a newer technology.
