Software Testing Strategies

Effective software testing will ensure that your application meets the standards of quality, performance, and security that you expect. Choosing the right software testing strategies and tools will help your team test more efficiently and stick to the timelines that you’ve laid out.

What Is Test Strategy in Software Testing?

Your software test strategy is a high-level document that outlines your team’s approach to testing. It is created during the early stages of the project and serves as a guide for the testing team throughout the development lifecycle.

A good software test strategy template should include:

  • Testing objectives: First you will define the goals and objectives of the testing effort, such as ensuring software quality, validating requirements, and mitigating risks.
  • Scope: Next you’ll want to outline the scope of testing, including what will and will not be tested, the features to be tested, and the testing environments to be used.
  • Methodology: Your methodology will be the testing approach and techniques to be used, such as manual testing, automated testing, black-box testing, white-box testing, etc.
  • Test types: This specifies the types of testing to be performed, such as functional testing, non-functional testing (performance, security, etc.), regression testing, and user acceptance testing (UAT).
  • Test levels: Even more specific are the different levels of testing to be performed, such as unit testing, integration testing, system testing, and acceptance testing.
  • Test tools: Once the tests are selected, you’ll want to select the tools and technologies to be used for testing, such as test management tools, automation tools, and performance testing tools.
  • Test environment: Your team will need to narrow down the test environment requirements, including hardware, software, and network configurations needed for testing.
  • Resource planning: Now that you have the tasks laid out, it’s time to select the roles and responsibilities of the testing team members, including testers, test leads, and test managers.
  • Schedule: Next you’ll want to lay out the testing timeline, including milestones, deliverables, and dependencies on other project activities.
  • Risks and mitigation: During this step, you will list potential risks to the testing effort and outline strategies to mitigate them.
  • Exit criteria: Your team will outline the criteria for exiting each phase of testing and moving on to the next phase or release.
  • Reporting: Lastly, you’ll want to describe the reporting and communication mechanisms for test progress, defects, and other testing-related information.

Manual Testing vs. Automated Testing

As you devise your software testing strategies, you’ll want to be sure that you’re taking the right test approach. One of your first steps should be figuring out what will need to be tested manually, and what can be automated to save time.

Manual can be a flexible approach that allows for exploratory testing, usability testing, and ad-hoc testing. It relies on human judgment to identify issues that automated tests may overlook, but it can be time-consuming, labor-intensive, and prone to human error.

Automated testing is suitable for regression testing, performance testing, load testing, and other situations where repetitive tests need to be run quickly and reliably. Automated tests are fast, repeatable, and can be run across different environments. Just keep in mind that the initial setup of automated tests will take a bit of time and not all types of testing are suitable for automation.

Types of Software Testing

Learning the different software testing strategies will help you build a workable schedule and plan to finish everything on time.

Performance Testing

Performance testing evaluates the speed, responsiveness, and stability of a software application under a specific workload. It helps identify and eliminate performance bottlenecks before the software is deployed. This type of testing ensures that the application meets performance expectations in terms of speed, responsiveness, and stability.

Types of Performance Testing

  • Load testing: Load testing helps determine the system’s performance under normal and peak load conditions.
  • Stress testing: This type of testing checks the system’s behavior under extreme conditions to determine its breaking point. It helps identify how the system behaves when subjected to stress beyond its capacity.
  • Endurance testing: An endurance test will look at the system’s performance over an extended period to ensure it can handle sustained loads.
  • Scalability testing: Scalability testing determines the system’s ability to scale up or down based on the workload.
  • Volume testing: This test helps identify how the system handles data storage, retrieval, and processing under high-volume conditions.

Security Testing

It’s essential that your team identifies vulnerabilities in the software that could be exploited by malicious users. Security testing helps ensure the confidentiality, integrity, and availability of the software and its data, and it’s crucial for protecting sensitive information and ensuring that the software is safe against potential threats.

Types of Security Testing

  • Vulnerability assessment: A vulnerability assessment will prioritize and address security issues based on their severity.
  • Penetration testing: Penetration testing simulates real-world attacks to identify security weaknesses. It helps identify potential entry points for attackers and assesses the effectiveness of the software’s security defenses.
  • Security auditing: An audit, such as SAST or SCA, reviews the software’s code and configurations to ensure compliance with security standards.
  • Ethical hacking: This approach uses white-hat attempts to breach the software’s security defenses with the owner’s permission to identify vulnerabilities.

Regression Testing

This category of testing ensures that new code changes do not adversely affect the existing functionality of the software. Under regression testing, your team will continuously retest the modified parts of the software along with the unchanged parts to verify that the software behaves as expected after changes are made.

Types of Regression Testing

  • Unit regression testing: Unit regression testing tests individual units of code after changes are made.
  • Partial regression testing: This type of test checks only the parts of the software that are affected by code changes to help save time.

Mobile Testing

The majority of online traffic comes from mobile devices, which is why mobile testing is so important. You will need to evaluate the functionality, usability, and consistency of a mobile application across different devices, platforms, and networks.

Types of Mobile Testing

  • Compatibility Testing: This ensures that the app works across different devices, platforms, and screen sizes.
  • Usability Testing: Usability testing evaluates the app’s user interface and user experience.
  • Performance Testing: This type of test checks the app’s performance under various conditions, such as low battery and poor network connectivity. It helps ensure that the app performs well under different circumstances and provides a smooth user experience.

Software Testing Best Practices

Check out some best practices that are based on years of industry experience.

Start Testing Early

It’s almost always a good idea to start testing as early as possible in the software development lifecycle (SDLC). Early testing helps identify defects in the initial stages of development which makes them easier and less costly to fix. By starting testing early, you can ensure that the software meets its requirements and functions as expected.

Define Clear Testing Objectives

Your testing objectives should guide your process by outlining what you want to achieve with the test, such as verifying a specific functionality or uncovering potential defects. Clear objectives help focus the testing efforts and ensure that the tests are meaningful and effective.

Use a Combination of Software Testing Strategies

To maximize test coverage and effectiveness, it’s beneficial to use a combination of manual and automated testing strategies. Manual testing allows for exploratory testing and human judgment, while automated testing helps in executing repetitive tests quickly and efficiently. By using a mix of testing strategies, you can maximize test coverage with an efficient use of resources.

Create Comprehensive Test Cases

Comprehensive test cases are essential for ensuring that all aspects of the software’s functionality are tested thoroughly. Test cases should be detailed and cover a range of scenarios and edge cases to uncover potential defects.

Collaborate Across Teams

Testing is a collaborative effort that involves developers, testers, and stakeholders. It’s important to foster collaboration and communication among team members to keep everyone aligned on testing objectives and software testing strategies.
