Software Development Life Cycle (SDLC) signifies the importance of any hardcore coding or implementation using the various tools available in the IT world. But when the time comes to see the authenticity of the development cycle or can say the final result of the cycle then the question comes what is needed to check it? The answer is Software Testing.
Dedicating a whole segment from SDLC, software testing holds primary importance in development of any software. In simple words, it is going to check that whether the created software is useful enough for usage or not. Moreover, there are various type of software testing that indulges you to take the usage of the software a bit ahead and bring new updates and versions based on the faults of the previous ones.
Ultimate objective of any software is to run properly without bugs but the aesthetic importance of that software is only maintained when the usage of the software is in definitive form with full compliance to user needs. The testing cycle hence can be divided into three simpler versions which can go step by step in a procedural mannerism. These steps are as follows:
- Unit Testing – As the name specifies, it checks each and every unit of the encore software for finding any kind of bugs or errors.
- System Testing – After unit testing, it is time to join the units to make a whole system and then apply system testing to see whether all the components are working in optimized mannerism.
- Regression Testing – This stage comes when you have already tested the software once and have a report based on the outputs. Regression testing ensures that after testing it again you will get same or better results from the software. This is very important to see the stability of the software in concern and hence the most important step of this cycle.
The overall concept of software testing is to get good quality and assured effective outputs. This means there should be no defects, working well, and system has the functionality for which it is created at first place. Many times it happens that after testing for a period you are releasing the software but after it is used by many end users, you come to know about its various faults and issues. At this moment, you need to understand that what exactly software testing is all about.
What is software testing?
Work comes first and then comes the issues related to it but as it is wisely said that “prevention is always better than cure”, it is rightly followed by using software testing. The façade of software testing is attached to its simple objective. This is to achieve an output based on the case studies. When you case studies, you may think that it is some kind of rocket science performed by officials of high grades and scholars. The fact is that these case studies are actually your day to day experiment with the software in concern.
Software testing is all about the case studies and then the various steps taken in performing those case studies. Now this can be in simplest mannerism as well. For example, you are going to take a shower and using soap. This process can technically be seen as a part of the cycle of testing the software. The main difference between this testing and IT world testing is that the entity is a part of the non-technical division. The output is based on the response of the user i.e. the person using the soap. Similarly, another person using the same soap will have some different views regarding the soap.
Maintenance process is closely associated with software testing. Based on the facts and information gathered from software testing, end users or owner requires maintenance which can also be known as brushing up the already created entity. One of the biggest examples in this genre is Microsoft Windows Vista. Originally, when it was launched in the market, it created a great hype that even captured the world before its release. Finally, when Windows Vista OS was released then it was found to be a very static implementation of the OS by Microsoft. The company took this into notice and stopped further versions of Vista from releasing and then came Windows 8 removing all the bugs.
So what happens if software testing is not performed? The answer is simple and you might have guessed it till now. Issues won’t be known to you at a stage where you should know and fix it. You will release the software to end users and soon the defects will result in the falling of this software with new allocations and software based on your theme would get released. Hence, software testing is an essential part to understand in the whole SDLC and comply with deliverance at optimum quality is always an option for you.
Software testing tools
When you are planning to begin the testing routine for specific software, then you need to figure out which tracking system to use. This term tracking holds an indefinite response from client side. Some of the most useful tracking systems that come into play in testing are as follows:
- Bug Tracking Systems
- Task Tracking Systems
- Issue Tracking Systems
- Defect Tracking Systems
These are the four major arenas where the systems work dominantly to provide bug free report, task handling in proper manner, issue handling procedure, and defect if any. The team members responsible for the mentioned task are assigned to job to fix the problem, either in an individual mannerism or in groups. Finding the solution to eliminate the problem is the only objective of software testing tools.
Currently, automated tools are in fashion due to its wide acceptance and good results. Just like testing software through different methods, there are abundant numbers of software testing tools. Choosing the right one and the most suitable one is in your hands. Software as a Service (SaaS) is a methodology model in software testing which will be discussed later after knowing about the various points about software testing life cycle.
Software testing life cycle
Being a core part of the Software Development Life Cycle (SDLC), software testing has its own life cycle by which it follows and checks the software at various stages. This in whole is known as Software Testing Life Cycle (STLC). QA process holds a valuable place in testing. Asking questions form clients, taking their opinion about already present software quotient, and many other factors sum up and cohesively make this life cycle which is followed as a thumb rule in all kinds of testing. The various cycles and its implementation in the software testing life cycle are as follows:
- Requirement Stage – This is the time when the client comes in action and you ask questions to know what he wants in the final outcome of the software.
- Test Planning – Based on the client’s response, you choose your test plan and set rules accordingly how many other people to include and what will be the core part.
- Test Analysis – Analyzing the test is also a valid step to see the compatibility of the expenses to the income gained through the project. Many times the expenses on testing increases at a great stage and that are quite negative things.
- Test Design – Tools are coming into play here and this is where you decide what software tracking system you would implement and what kind of software testing tools will come into play.
- Test Verification and Construction – After executing the test design you need to move forward and construct the methodologies for the testing procedure. Verification also needs to be done at this stage to see that the kind of test you are using is compatible with the software.
- Test Execution – Finally, the assigned members work independently and execute the test plans and follow all the procedure mentioned in the construction.
- Result Analysis – To check the end product after testing the software is also a task that needs to be done by experts and for that you need to thoroughly use the software.
- Bug Tracking – Mentioned before, this is where you fix the errors and the drawbacks in the project or software on which testing is done.
- Reporting and Rework – Fixing the problem is actually preceded with the tracking system and then reporting and reworks are done on the software.
- Final Testing and Implementation – Final report and implementing the testing is the next step that follows the life cycle of testing.
- Post Implementation – After testing and the whole cycle has taken a round, there is an extra circle which is post production of after implementation of the testing cycle.
Test Design and the methodologies hold an important section in the whole cycle. Further, it is noted that what kind of testing has been done before so that next time you can bring a little change and proceed with the testing phases.
Software testing methodologies
Some of the most important facts about software testing hold its importance in the methodologies it implements. Software as a Service (SaaS) is one of the basic methodologies which make software testing a genre in the service class of IT industry. Software testing methodologies provides functionality and quality assurance as a continuous scale form.
