How To Write Test Cases For Automation Testing

How To Write Test Cases For Automation Testing – Reducing testing costs is often the first thing organizations think about when adopting test automation. After all, software testing is incredibly expensive; It accounts for an average of 23% to 35% of global IT spending, according to the latest World Quality report. Test automation allows you to focus on more interesting and value-added tasks, while performing routine tests faster, more often and with greater accuracy.

Obviously, the value is there. However, even open source testing tools require an investment in resources, and this requires someone more advanced to buy in. How do you convince the business that test automation is worth the time, effort, and expense?

A typical approach is to calculate a simple ROI: calculate how many hours of manual testing you can free up, and then multiply that by the testers’ hourly rates. This is certainly a good starting point. But elements of a strong business case for test automation include time-to-market, quality/risk, and a much broader ROI assessment.

Time to market is all about how quickly you can get a new feature or update in front of the end user. The longer you take to release new features, the less flexible you are and the more difficult it becomes to respond to dynamic customer needs and emerging market trends. Depending on the nature of the application, delays may adversely affect your revenue, operating efficiency and/or competitive advantage.

Given that testing is commonly cited as a major source of delivery delays, it’s fair to say that time to market is highly dependent on testing efficiency (how well you can execute tests quickly).

Testing efficiency, in turn, is based on the time taken to perform automated testing (including preparation, execution, and analysis) compared to conventional testing (again, including preparation, execution, and analysis).

The greater the difference, the greater your potential to time the market. And the more often you take tests, the bigger the payout.

Risk reduction is all about how many defects you can prevent from entering production. Runaway defects bring a number of problems. You’ve probably seen the curve that shows how fixing defects after release is exponentially more expensive than catching them early. But there’s also downtime, support costs and, in many industries, fines to worry about.

Knowing your business’s risk coverage is key to assessing risk mitigation. Determining this involves ranking the risks of your requirements or use cases against each other, mapping tests to risk-weighted requirements, and tracking how well your testing covers your highest risks.

It is quite possible that 10 strategically designed tests will achieve much more risk than 100 risk-free tests. The greater the risk coverage, the lower the defect density.

The third component is what people usually think about first: What time and costs can you save by testing more efficiently? With automation, you can run more tests at once—or you can run the same number of tests in less time.

You can find many quick and dirty formulas online, but finding an accurate one depends on several factors. Be sure to consider things like:

Deliveries are expected to be nine times faster once the company shifts a significant portion of manual testing to automation (see figure below). An increase in testing frequency will result in almost 10 times more defects being detected in the test (from 650 to 5649).

Although automation testing is becoming increasingly popular, there are still some difficulties for automation teams, including choosing which test cases to automate. According to the 2019 World Quality Report, 24% of teams face obstacles that prevent them from deciding on the right test scenario. This article will detail how to select test cases for automation and maximize your testing journey.

According to the latest 2020 Test Automation Landscape Report, 50% of test projects are automated and this number is expected to increase. Test automation not only solves the problems of human error in testing, but also increases test coverage and speed, thereby improving ROI for the entire project.

In software testing, a test case is a detailed document of the specifications, inputs, steps, test conditions, and expected results associated with the execution of a software test (AUT) on a test program. There should be at least 2 test cases for the desired coverage for a feature: a positive test case – where the input is valid – and a negative test case – where the input is invalid. Therefore, most testers combine multiple test cases into a test suite for most coverage, allowing for easier testing and maintenance.

With this you can see the importance of choosing test cases for automation. Not all tests can be automated, and selected test cases are the basis for choosing and executing your automation tools. If you choose tests that are not suitable for automation, you risk wasting time and resources rather than saving them.

First, testers should strengthen their knowledge of two elements: AUT testing requirements and their team’s capabilities. Teams can then weigh these facts against the benefits of test automation and envision all the areas where automation could be the answer.

With this in mind, there are several critical factors when choosing automation test cases that test teams should consider:

Before automating any test cases, teams should carefully compare these test cases against a set of criteria. Below are the test cases recommended for application automation.

Although test automation is a promising solution for quality and speed in the process, automating every test case will do you more harm than good. To avoid overdoing or abusing automation testing, there are a few golden rules when it comes to the unmanned part of automation testing:

Define the parameters on which you will evaluate automation test candidates. Teams can then break down the AUT module in tests and rate it against the criteria above. Before finalizing the selection, perform ROI measurements as a final filter and as criteria for automation results.

The expected ROI calculation is measured by the result. There are also other measurements specific to each level (project, department, company, etc.) that the team can calculate to measure the effectiveness of the automation process.

Depending on the nature of the project, test automation certainly requires high initial investments, and their income may not be visible even in the next 3-4 years. Therefore, in order to visualize the ROI (return on investment) from such investments, any management wants to first see and evaluate a properly planned business case.
