What is automation testing?
Automation testing is a method of software testing using automated tools. It comes in parallel with software development; QA team, before starting of automation testing determines the scope, selects the right tool for automation, develops a test plan, test design and test strategy, sets up the test environment and after that writing test scripts.
Automation testing is good to perform repetitive tests without continuous involving people, so automation testing is faster, enhances efficiency and requires fewer human resources. A good software company will never skip automation testing because it gives maximum results and ensures the overall quality of software.
After all the preparatory work is done, QA engineer writing the test scripts in a related programming language using a testing framework. There are different frameworks for different languages.
What types of software testing can be automated?
Unit test is evaluating the code of the software. Checking out the methods/functions, classes, variables, and modules. The unit test is said to be an ordinary test that can be held quickly.
Integrations test is verifying the compatibility of different modules of software with each other. For example, a school software has a portion for staff attendance and another for their salaries, salaries are deducted if there are absent, so, integrations test will be performed to verify whether these two modules work together. This type of automation testing is expensive and time-consuming.
Software performance testing is checking the software under load and stress. It is preferred to perform it once manually and then automatically to eliminate any errors. Major purpose of this type of testing is ensuring software quality and stability.
It holds smoke tests to check the basic functionality of the software. They are held after a new feature/module is completed to determine whether the software is ready to move on to new modules.
Regression testing has nothing new but re-execution of already executed tests to confirm that a new feature or piece of code has not negatively affected the existing features. It is performed in case of a new feature is added, defect fixing or a performance issue is fixed.
Acceptance tests are end-user oriented tests that confirm if the software fulfills the specified requirements. The acceptance test is performed at the end of development and whole software is evaluated and if it misses certain goals, it reverts to the development phase.
Top 10 Benefits of Automation Testing
Quick Feedback During the different stages of a software project, the process of automated testing serves as a relief for validation. This process of testing helps to improve the communication level between the designers, product owners, and the coders. This will allow the serious issues to be quickly resolved. This process of testing will help to improve the efficiency of the development team.
Faster Results When the process of automated testing will be used this will help in saving lots of time even for huge and complicated systems. This will allow ease for testing to take place repeatedly and provides better results this will take less effort and time than before.
Business expenses are reduced An initial investment in any business appears to be on the higher side. But automated testing will help to save lots of money for the companies. This is mainly because of the reduction in the time spent to run the tests. This will ensure the quality work, as a result, the issues that appear after release will be solved and it will reduce the project cost.
Overall improved test coverage Before the process of automated tests is implemented, more tests can be performed before the release of an application. This will help to improve test coverage. Because manual testing will require lots of team members and time to perform the test. Better the test coverage better will be the more features and better will be the application.
Reusability There is always a need to repeat manual tests whenever required, but the best perk of automation testing is reusability. Once a test script is written we can use it for any number of times. Sometimes it requires a minimal change to scripts, but that still saves QA specialists a lot of time and effort.
Quick defects detection The process of documenting the faults of software becomes easy for the team performing tests. As a result, the development speed will be increased and the right functionality between the areas will be ensured. As soon as it will identify the fault the more cost-effective, it will be to resolve the issues.
Detailed testing There are different testing techniques that are used by the QA engineers. And depending upon the exposure and expertise they have their focus areas could be different. With the addition of the process of automation, all the functional areas are covered and the best quality product is produced.
Entry time to market will be reduced The process of automation testing will reduce the time of application to get into the market. Once the process is adopted, it helps the execution of a library to be faster and is used for long terms than the manual testing process.
Less Manual Effort If you use automation testing system, it will save a lot of efforts by quality assurance engineers. Automation testing cut the cost of using more resources.
Enhanced ROI and Security Return over investment is the most concerning aspect of an organization. A software company that develops software for the market must want something big in return for their time and investment. Automation software testing ensures the best return over your investment because it saves time, gives better results, increases the quality and cut the prices over resources.
Automation testing also does accuracy, we mean the error-free working of automation tools. Once a test script is written and works fine, it will work the same in every attempt. In manual testing, engineers write information and data on plane papers or doc files that has a data stealing factor. In Automation testing information is secured in a database that is more secure and invisible to a layman.
