I want to know the best approaches (Automated UAT, Regression testing, Retesting, etc.) to reduce production defects in software development.

All of the above.

Most importantly, a finely detailed test plan.

Testing starts during development but unit testing and end to end testing specific changes. Next would be integration test of all changes togeather.

Regression testing is used to ensure new changes are not breaking already established and working code.

UAT is the requirement of code quality to be accepted by the user. It must meet a baseline in order to be promoted to a production environment


Automation is a tool you can use to perform some of these tasks, but its not a test process. Not to be rude but it would appear you need a lesson in how Test process works and what needs to happen to ensure code quality.

Manual and Automation testings have important roles to play but one needs to be aware of when to make use of the right one. 

  1. Time Consumption and Cost to the Company

In a project where the content is large and the testing phase runs for quite a long time, automation testing is the perfect choice since

  • It reduces the number of resources required.

  • Multiple types of similar test case scenarios can be executed simultaneously with a single script.

  • For a large project, the estimated budget is sufficient enough to afford the setup and maintenance of an automated testing tool. However, in small projects where the testing phase runs for only a few weeks, Manual testing is more preferable since:

  1. False Positives and False Negatives- A false positive is a scenario where the system is fundamentally working fine but the automation scripts show otherwise. This could cost a tester a huge amount of his time and money for finding something which doesn’t even exist. Vice-versa, a false negative is a scenario where the automation script declares the system to be working fine when in reality, it isn’t! This happens if the initial stage of a database is inaccurate or if test environment settings are abrupt due to network issues. So even if you do have automation testing the accuracy of test results will still not be guaranteed.

  2. Cloud Computing Softwares are vastly dependent on automated testing tools. The reason being that the resources shared on the cloud is supposed to be accessible by anytime, anywhere and by anybody with an internet facility. So testing whether your software is working as intended all day & everywhere could not only be very tedious and faulty if done manually. But it could also be highly time-consuming. If you are worried about your product instability and have a long list of test cases to perform on daily basis then automation testing can ease your life.

  3.  Regression testing is made considerably effortless with the help of automated scripts.


You can use a platform like QAppAssure which allows you to test on-cloud and on-field devices, across 100+ device, make and models, Integrate with Jira, CI/CD tools, and also use Appium, Calabash, Espresso, UIAutomator, XCUITest.

Employ following task to minimize the production defects in software development: 

  1. Change the Groupthink Regarding Defects
  2. Thoroughly Analyze Software Requirements
  3. Practice Frequent Code Refactoring
  4. Perform Aggressive Regression Testing
  5. Execute Defect Analysis
  6. Consider Continuous Changes
  7. Integrate Error Monitoring Software

When it comes to software development and defects during production, the only thing that I believe restricts the testers to explore every component leading to defects is some stereotypes. Though there are certain best practices made to improve the process, it is vital that testers should change their approach about defects to explore new dimensions of the product.  


Furthermore, defect analysis should begin with QA services taking over the requirements of the product so that product can be tested for defect analysis after rapid regression testing sessions. This would help testers to learn any possible areas of fault and change the programming to improve the outcomes.

There are numerous ways to reduce production defects. To avoid those we have to follow these steps.

  1. Peer code reviews – static testing.
  2. Continuous Integration.
  3. Test in a QA environment.
  4. Perform regression testing.
  5. Effective production defect tracking.
  6. Empower testers to make project recommendations.
  7. Add a warranty period.
