Frequently Asked Questions

What is software testing? Why is it important?

The process of examining a software product to ensure it performs its intended function and fixes the defects is termed software testing. Software testing helps developers build flawless software solutions free from data vulnerabilities. Performing rigorous software testing can improve software quality, increase user data security, enhance customer satisfaction, reduce bugs, and save money.

What are the benefits of software testing?

The benefits of software testing are identifying bugs, addressing the issues in the development cycle, ensuring the quality and the success of the product, accelerating the development process, securing compliance, reassessing the vulnerabilities, reducing the mitigated risk associated with software projects to enhance software reliability, improving the user experience, saving time and resources.

What are the different software testing methodologies?

The different software testing methodologies adopted by software testing companies are waterfall testing, sequential testing, agile testing, DevOps testing, continuous testing, spiral testing, risk-based testing, model-based testing, behavior-driven testing, and exploratory testing. Each of these testing methodologies leveraged by testing service companies has its own advantages and selecting the method is purely based on the project requirements.

What are the types of software testing?

The types of software testing are unit testing, integration testing, functional testing, non-functional testing (performance, security, compatibility accessibility, reliability, and usability testing), system testing, smoke testing, regression testing, user acceptance testing, exploratory testing, adhoc testing, and complete end-to-end testing.

There are two chief software testing types:

  • Functional Testing
  • Non-Functional Testing

1. Functional Testing:

Functional testing authenticates the software system against operational requirements as well as specifications. The main goal of functional testing is to verify critical system operations, basic usability, and accessibility while checking for error conditions.

The four main Functional Testing categories are as follows:

  1. Unit TestingUnit Testing is a process that concentrates on individual components of the software to ensure that the system operates as expected. It assists software testers in identifying and fixing bugs and defects in the early stages of the development cycle, allowing coders to modify the code as needed.

    Automated as well as manual testing can be conducted for unit testing. Testers can isolate groups of code and perform rigorous testing, which helps to identify unnecessary dependencies between the codes that should be eliminated. One of the most important benefits of unit testing is that it allows programmers to restructure existing codes to ensure the module functions flawlessly.
     
  2. Integration TestingIntegration testing logically assembles software modules in a group and tests them. This allows testing service providers to identify and resolve bugs hindering communication between the software modules. Integration testing also covers the impromptu changes made in the software, which might not have been unit tested.

    Integration Testing checks data flow between software components. Two approaches are available - Big Bang or Incremental. It analyzes the interface link between the login and home pages to ensure the user is directed to the software's main page.
     
  3. System TestingSystem testing validates the complete application. It ensures that the end-to-end functioning of the system meets the quality standards set by the client. System testing is generally performed by independent software testers who haven't contributed to the development of the software in any way. This ensures that the results and reports delivered are accurate and unbiased.

    Automated software testing involves analyzing the outcome of every input in the system to ensure that the desired outputs are achieved and that users have a positive experience. In addition to validating business requirements, system testing verifies the application's architecture.
  4. Acceptance TestingAcceptance testing, also known as User Acceptance Testing (UAT), is performed to assess whether the system is ready for deployment. Clients or end-users do these tests to ensure the integrity of the application. During software development, there are chances that specific user requirements may not be adequately communicated to the developers. This may result in developing a highly different system from what the user requested.

    Acceptance testing implements the following steps.
  • Analysis of Client Requirements
  • Distinguish Test Scenarios
  • Formulating UAT Test Plans
  • Test Cases
  • Record Results
  • Confirm Objectives

Once this testing procedure is completed and the system passes the tests, the program is moved to production.

2. Non-Functional Testing:

Non-functional testing verifies non-operational aspects of software, such as performance, usability, and reliability. It assesses readiness beyond functional testing.

For example, Non-functional Testing checks the number of people who can simultaneously log in to an application.

The key objectives of Non-functional Testing are:

  • Increase usability, maintainability, efficiency, and other criteria of the product.
  • Decrease production risk and cost.
  • Optimize product installation.
  • Accumulate metrics for internal R&D.

The following are the different software testing types of Non-functional testing modules:

  • Installation: Installation testing detects and resolves any errors during software installation.
  • Localization: Software testing companies assess the software for it to work according to the culture and setting of the deployment location.
  • Performance: As the name suggests, performance testing is done to warrant the smooth working of the software.
  • Recovery: Software testing companies must ensure that after any sudden crash in the system, it must be easily recoverable. This is analyzed during Recovery Testing.
  • Reliability: Reliability testing checks the extent of the software system to which it can continuously perform specific tasks without hindrance.
  • Security: This parameter defines how software is safeguarded against sudden or deliberate attacks from internal or external sources.
  • Stress: Stress testing studies the limit of the software with an increased workload to which it can operate without lagging.
  • Usability: This ensures the user can learn, operate, and communicate with the system effortlessly.
  • Volume: The software testing service providers maintain the system's capacity to handle massive data without affecting its response time.

Apart from the above-mentioned, testing service companies also offer Automation testing, Compatibility testing, Compliance testing, Load testing, etc.

Businesses can also opt for additional software testing tools to improve the implemented software testing techniques. Some popular software testing tools are A/B testing software, QA testing software, Beta testing software, etc.
