Why is software testing important?
During the development of the software, there is a chance of bugs or errors in the software which must be identified early and should be solved before delivery of the software product. It really helps because properly tested software products are highly reliable, secure, and serve high performance which results in time-saving, cost-effectiveness and customer satisfaction.
What are the benefits of software testing?
Security
It is one of the best benefits of testing as it provides security for vulnerabilities. People always look for trusted products where their data will be safe. It helps in the same by removing risks and problems earlier.
Quality of product
It is one of the most key factors as every customer wants a quality product and testing ensures that the quality of the product is going to be delivered to the customer.
Cost-effective
It is one of the most important advantages of software testing. If your testing is going hand in hand with development it saves a lot of money and time.
Customer satisfaction
The ultimate goal for any company or enterprise is customer satisfaction in order to scale business and that can be done by providing above mentioned facilities. UI/UX testing ensures the best user experience.
Life Cycle of Software Testing
It is a sequence of different activities performed by the testing team in order to make product error or bug-free and deliver a quality product. It also finds which text activities have to be carried out and which activities have to be accomplished. In the life cycle, each activity or each phase is done in a planned and systematic way.
1- Requirement analysis
this is the first step in the life cycle and this quality assurance team understands the requirement in terms of what they have to test and figure out the testable requirements.
2- Test planning
it is the most important phase as all strategies are defined and this phase is also called Test Strategy. The Test manager is involved in this phase to determine the effort and cost estimates for the whole project. It also defines the objective and scope of the project.
3- Test Case Development
This step is started after the test planning and in this, all test cases are noted and planned to test. Along with the test cases, the testing team also prepares the test data for testing. Once the test cases are done or ready then they are tested by quality assurance leaders.
4- Test Environment Setup
it is one of the vital parts of the software testing life cycle as it is a setup of software and hardware for the testing team to execute test cases. It also supports the test execution with hardware, software and network configured.
5- Test execution
In this step of the software testing life cycle process of executing the code and comparing the expected result with the actual result. Once the test execution starts, the test analysis starts executing the test scripts based on the test strategy allowed in the project.
What are the different types of Software Testing?
In the above topics, we have discussed the benefits and the life cycle of software testing. Now further it is important to be aware of various types of testing which are generally of two types
1- Manual Testing
It is the process of testing software by hand or manually to get deep and more information about it, to find what is working and what is not. This encompasses the verification of all the features specified in documents. Before delivering the final product to the customer, the tester itself tries that software to ensure whether the software is meeting the exact requirement or not by keeping all circumstances of the end user’s requirement. The plan of the manual test varies from fully scripted test cases which give all detailed steps and expected results to the tester.
2- Automation Testing
In this automation testing tools are used to control the execution of tests and then compare them with the results against the expected or required outcomes to figure out the defects. Basically in this process, testers execute the given test scripts and generate the test results automatically with the automation tools. There are multiple popular tools which are well-known for software testing such as Selenium, testRigor, and Katalon Studio. Among all these Selenium is popular for web application testing and it has the most powerful capabilities like cross-browsing testing.
Now, there are also various testing methods for different software or applications and they are further classified into two types-
Methods Of Testing
1- Static
It is also known as verification in software testing. Generally, verification is a static method of checking documents and files. It is the process where we ensure that the product we are building is going right or not i.e., in simple terms to verify whether we are developing the product accordingly or not.
2- Dynamic
This method is also known as Validation in software testing. In this process validation of the product is done i.e., whether the product we have developed is relevant or not.
Now, we have adequate information about software testing. But it is necessary to know the right time to start and stop this testing.
The Right Time to Start
Based on the selection of different models of software development life cycles, testing can be performed in various phases of development. There is a myth all around that testing should be or can be done only post-development of the project which is a completely false way and this may even cost you more than expected. Testing should be done in parallel with the first line of coding of the project. It becomes easier to build efficient and high-performance software with minimal errors. This also saves your lots of money and time.
The Right Time to Stop
It is quite tough to answer when to stop testing or when the system or software is 100% free. Because it will be false to commit that any software is 100% bug-free even a specialist tester can’t commit that. Still, there are some phases through which we assume that our project is meeting the requirements.
- Sufficient pass percentage
- Successful test case execution
- On meeting deadlines
- Mean time between failure
Conclusion
The above article is holistic software testing information which is relevant and must be known by beginners who are looking for a dynamic career in the same. One should go for Software Testing Training for professional training from a well-established institute. It opens a wide range of career opportunities with handsome salaries and even in high demand.
