Tips for effective quality control practices

 Define clear quality standards: Establish clear quality standards and communicate them to the development team. This can include performance expectations, user experience, and other factors that affect software quality.

Use automated testing tools: Leverage automated testing tools to increase efficiency and reduce errors. This can include tools for functional testing, performance testing, and regression testing.

Conduct frequent code reviews: Regular code reviews help identify issues early in the development process. This can help reduce the number of defects that are introduced into the codebase.

Use test case management tools: Use a test case management tool to manage and track test cases. This can help ensure that all test cases are executed and that results are tracked and reported accurately.

Perform exploratory testing: In addition to scripted testing, incorporate exploratory testing to identify issues that may not be caught by traditional test cases. This can help identify usability issues and other defects that may impact user experience.

Use performance monitoring tools: Use performance monitoring tools to identify performance issues in real-time. This can help reduce the impact of performance issues on end-users.

Develop a strong feedback loop: Establish a strong feedback loop between the development and testing teams. This can help identify issues early and ensure that all issues are addressed in a timely manner.

By implementing these tips, software testers can help ensure that software is of high quality and meets the needs of end-users.

Software Testing Types

These are some software testing types,

• Black box testing: In black box testing you don't need to know the internal design in detail or have a good knowledge about the code for this test. It's mainly based on functionality and specifications, requirements.

• White box testing: White box testing based on detailed knowledged of the internal design and code. Tests are performed for specific code statements and coding styles.

• Integration testing: Testing of combined parts of an application to determine if they function together correctly. It can be any type of application which has several independent sub applications, modules.

• Functional testing: Black box type testing to test the functional requirements of an application. Typically done by software testers but software programmers should  also check if their code works before releasing it.

• Unit testing: The most micro scale of testing to test specific functions or code modules. Typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code.

• System testing: Black box type testing that is based on overall requirements specifications. Covers all combined parts of a system.

• End to End testing: It's similar to system testing. Involves testing of a complete application environment similar to real world use. May require interacting with a database, using network communications, or interacting with other hardware, applications, or systems.

• Regression testing: Re-testing after software is updated to fix some problems. The challenge might be to determine what needs to be tested, and all the interactions of the functions, especially near the end of the sofware cycle.

• Sanity testing or smoke testing: An initial testing effort to determine if a new sw version is performing well enough to start for a major software testing.

• Load / stress / performance testing: Testing an application under heavy loads. Such as simulating a very heavy traffic condition in a voice or data network, or a web site to determine at what point the system start causing problems or fails.

• Usability testing: Testing to determine how user friendly the application is. It depends on the end user or customer.

• Security testing: Testing to determine how well the system protects itself against unauthorized internal or external access and intentional damage.

• Compatability testing: Testing how well software performs in different environments. Particular hardware, software, operating system, network environment etc. Like testing a web site in different browsers and browser versions.

• Install / Uninstall testing: Testing of full, partial, or upgrade install / uninstall processes.

• Recovery / failover testing: Testing to determine how well a system recovers from crashes, failures, or other major problems.

• Alpha testing: Testing of an application when development is nearing completion. Minor design changes may still be made as a result of such testing. Typically done by end users.

• Beta testing: Testing when development and testing are essentially completed and final bugs and problems need to be found before final release. Typically done by end users or others.

Software Testing Basics

Before I discuss about Software testing let us be a bit aware about why do we need to test the software? What is testing?  

We need to test any software to determine the requirements of it before framing software. We need to test any software to determine if the software application is complaint to the requirement gathered before building it. Testing also ensures the quality of software. In simple words we can define the “Testing is a process by which helps to certify the correctness and completeness of a software application to the required document under controlled environment”. Simply software testing is the process of executing the program and finding the errors or we can call it bugs.

Software bugs almost exist in any software module, not because programmers are irresponsible or they are careless, this is because of complexity of software. The technical faults of the software are uncovered which is not possible without testing.

Simply testing is required,

•    To detect fault of the product/software.
•    To develop quality and bugs free product.
•    Avoid user detecting problems and saving the testing time.
•    Give quality product/bug free product to end user.
•    Reduce the rework.
•    Testing reduces maintenance cost.
•    To ensure that software is behaving as per customer expectations. 

How to test the software application: 

1)    With the help of manual testing.
2)    With the help of automation testing.
3)    Both Manual & automation testing.

This is basic information on software testing; you can check more blogs for details on Black box testing, White box testing, Gray box testing, etc.
