How is QA Testing Relevant in-App Development Lifecycle?

Testing combats all fallacies and misconceptions about implementing testing during SDLC!

Organizations of all sizes struggle to combat some ingrained partialities. There is a particular pattern of bias against static testing, which gets a bad rap even though it helps avoid costly errors early in the development cycle. It forfeits high initial costs and potential time delays, which makes companies engage in it.

Differences: The Tussle between Static and Dynamic Testing

Static testing is time-intensive, uncovers mistakes that are insignificant to endanger the application. It does not test the code, and static analysis tools do not reveal if client requests are met. Therefore, it is pertinent to balance pointless and imperative, and simultaneously avoid time delays.

Also, static analysis helps catch only up to 10% of quality defects. Therefore, static testing is incapable to cater every software quality defect. There can be challenges in performing static testing automatically. Automated tools only scan the code, and are incapable of separating weak points that may cause problems during runtime. It also does not validate interfaces and how each segment will interact with the other. It also does not ensure how the system will perform under load and how susceptible is it to hackers or the degree of user-friendliness.

Benefits: The Importance of Testing in App Development

Testing is most fruitful if implemented in the earlier stages of the software development life cycle.

Purpose: How should you justify the need for testing?

It is very important to know the investment-gain ratio while planning to start with testing, once development completes. To justify the static testing return on investment, follow these steps:

  1. Calculate the total hours spent on static testing.
  2. Translate those hours into a dollar amount.
  3. Convert the number of defects found through static testing into the number of hours required to fix them through traditional testing.
  4. Convert the proposed number of hours for testing into a definite dollar amount.
  5. Step 4 – Step 2 will give you the sum of hours applicable in static testing in the development cycle.

Role: What can systematic testing achieve for you?

Testing can accomplish the following business objectives for you:

What is the role of the QA tester in SDLC?

Software applications are never complete without rigorous stages of software testing. It takes place in stages of test case creation, creating unit tests (created by developers), Alpha-beta testing, regression testing, stress/load testing, smoke testing, preparing system tests, integration testing.

Delivering the best user experience and improving the software is impossible without testing efforts.

The role of software testing in SDLC involves completing the phases of the Software Testing Life Cycle (STLC). It is not equivalent to quality control. It is not easy. It requires running test scripts and executing SQL queries to get things done. There are specialized and skilled people to perform software testing.

Software testing life cycle (STLC) includes:

  1. Requirement Analysis
  2. Test Planning
  3. Test Case Development
  4. Test Environment Setups
  5. Test Execution
  6. Test Cycle Closure

Major Roles Involved in Software Testing:

  1. STLC involves understanding the mindset and requirements of the clients. Although the application is developed in the lines of SRS and SDS, still the team may go too deep to include the most essential technical details ignoring the actual requirements. It, therefore, becomes ‘essential’ to check the exact requirements and compare them.
  2. It is pertinent to understand the platforms and the target devices.
  3. It is essential to design the strategy and the potential test scenarios. It helps understand the business needs and opting for correct testing techniques and the types.
  4. It is used in selecting the correct testing tools for automation testing – Selenium, Protractor, Cucumber, Apache JMeter, Appium, and LoadRunner. It helps simulate thousands of users from a single machine.
  5. Testing strategies and testing tools help optimizing tasks through writing efficient scripts using any language.
  6. Executing and re-testing scenarios is ‘important when there is the need to perform the risk analyses.
  7. Scheduling QA activities via testing tools and the available resources help to allocate the resources on the right tasks based on the code releases at the regular interval.

Major Tasks That Software Testing Does

Frequently Ask Question:

How often should you plan static testing?

Can you plan to build a house without planning the height of the ceiling or the size of the kitchen pantry? The software world seeks similar intuition from application architects and software test engineers. Static testing enables enterprises to identify defects, fix them, predict errors, and correct bugs before coding. But it saves organizations valuable time and money, offsetting the initial cost to carry it out.

Why is testing ‘important’ in the system life cycle?

Testing draws attention as it forms the basis of the developed application and makes it deployment-ready. It improves the (1) quality, (2) reliability, (3) performance of the system, (4) ensures the superior quality of the product, (5) reduces the overall maintenance cost, (6) provides better functionality.

Conclusion: What are the ‘key’ takeaways?

Testing at an earlier stage saves time, cost and resources as it enables picking various business models for mobile applications. It lets development teams describe how available mobile analytics data propels input for the test strategy and test plan. It alerts teams about how the potential risks to mobile apps.
