In our previous article, we made the point that coupling test execution to CI/CD pipelines has several drawbacks that become apparent as the complexity and scale of your application or deployment infrastructure increases. Let’s take a step back now and look at the initial need solved by CI/CD in this context: running your tests, which is also known as test execution. As with many things, giving test execution some extra thought and love as you build out your infrastructure can reward you in multiples. Let’s break it down.
The software testing life cycle (STLC) is a well-established step-by-step breakdown of testing activities in the software development life cycle (SDLC). Test design is a crucial preparatory activity that influences later phases by ensuring comprehensive, clear, and effective test cases. At a high level, the STLC consists of the following steps:

The test planning phase includes defining test objectives, creating a test plan, and establishing a test strategy to guide the testing process and ensure quality and traceability across all activities.
As you can see, test execution is a specific step in this life cycle, and it in itself is a rabbit hole to delve into. Let’s do just that.
As organizations scale their testing operations across multiple tools, CI/CD systems, engineers, and applications, managing test execution becomes increasingly complex. Effective test execution is fundamental to software quality and project success—it enables early issue detection, validates release readiness, and maintains market competitiveness.
This framework breaks down test execution into five manageable steps that can grow with your organization's needs.

Team Excellence: The test team plays a critical role in executing test cases across diverse testing environments and cycles. Well-maintained test scripts and automated test scripts ensure consistent, repeatable, and effective execution.
Comprehensive Coverage: Including system integration testing and performance testing in your test suites validates applications across multiple layers and scenarios. Executing all test cases ensures comprehensive coverage and software reliability.
Strategic Impact: Effective test execution directly impacts defect detection, release readiness, and stakeholder confidence, making it essential for achieving high software quality and project success.
Start by assessing your current state across all five steps, then prioritize improvements based on your organization's specific needs and constraints. Remember that this framework should evolve with your testing maturity and organizational growth.
Testing Environment Setup is a foundational phase in the software testing life cycle (STLC) that directly influences the accuracy and reliability of your test execution. In this stage, the testing environment is carefully configured to replicate the conditions of the production environment as closely as possible. While the testing team typically does not handle the actual setup—this responsibility often falls to developers or customers—it is crucial for testers to define their requirements and validate that the environment meets the necessary criteria.
A robust test environment setup involves configuring hardware, software, databases, network settings, and any required integrations to ensure that the testing process is both efficient and realistic. This alignment allows the testing team to uncover defects that might only appear under specific conditions, reducing the risk of issues slipping into production. By investing in a well-planned testing environment, organizations can ensure consistency across test executions, streamline the testing process, and ultimately deliver higher-quality software.
Apart from the somewhat tactical approach to test execution outlined above, we can define a number of criteria that need to be assessed and planned for to scale accordingly with the needs of your team and your application.
Consistency – Getting consistent test results is key to building trust in quality metrics and downstream activities, and to that end, your test execution environments should be as homogenous as possible, given the context of your applications.
Decoupling – Test execution should not be tightly coupled to any other specific framework or pipeline in your infrastructure. The need to run tests will shift both strategically and tactically over time, and your tests should be available for execution whenever needed.
Centralization – While your tests might execute in multiple places in your infrastructure, managing these executions and their results in one place gives you a holistic view of your testing activities, making it possible to assess, analyze and control test execution consistently as your testing scales with your applications and infrastructure. Maintaining comprehensive test case execution records and organizing test runs by test plans further enhances your ability to track, report, and assess testing progress and outcomes across different environments and iterations.
Integration – Test execution commonly needs to be integrated (but not tightly coupled!) with your existing workflows and pipelines.Scalability – Running tests at scale is one of the most common challenges for teams embracing a proactive approach to test execution.
Security and Access Control – This has several aspects:
During the test execution phase, each test case progresses through various test execution states, providing valuable insights into the health and stability of the software. Understanding these states and their outcomes is essential for interpreting test results and guiding further analysis.
The most common test execution states include:
By tracking these test execution states, teams can quickly identify which areas of the application require attention, prioritize defect resolution, and ensure that the test execution process delivers actionable and accurate test results.
Handling failed tests is a critical component of the test execution process, as it directly impacts the quality and reliability of the software. When a test case fails, it signals a deviation from expected behavior, prompting the testing team to investigate further. The process typically involves analyzing the failed test case, reviewing the test results, and identifying the root cause of the failure.
Once the issue is understood, the testing team collaborates with the development team to report the defect and provide detailed information for resolution. After the defect is addressed, the failed test case is re-executed to confirm that the issue has been resolved and that no new problems have been introduced. This iterative approach ensures that all failed tests are thoroughly examined and that the software meets the required quality standards before release. Effective handling of failed tests not only improves the test execution process but also fosters a culture of continuous improvement and collaboration between testing and development teams.
A Test Execution Report is a vital deliverable in the test execution phase, providing a comprehensive summary of the testing activities and outcomes. This report details the number of test cases executed, along with their respective statuses—passed, failed, or blocked—offering stakeholders a clear view of the testing process and overall software quality.
Key metrics included in a test execution report often encompass test coverage, test execution rate, and defect density, enabling teams to assess the effectiveness of their testing efforts. The report also highlights any critical issues or trends observed during the test execution phase, supporting data-driven decision-making for software release and future test planning. By maintaining detailed test execution reports, organizations can track progress, demonstrate compliance, and continuously refine their testing strategies for improved results.
Adopting best practices for test execution is essential for achieving efficient, effective, and consistent results throughout the software testing process. To maximize the value of your test execution efforts, consider the following guidelines:
By following these best practices, testing teams can execute tests more effectively, achieve consistent test results, and contribute to the delivery of high-quality software that meets business objectives.
The approaches outlined above are starting points, not exhaustive solutions. Every application infrastructure is unique, which means your team's testing needs will be equally distinctive. The key is to think beyond simply "running Playwright tests in Jenkins" — that approach will hit a dead end and prevent your testing activities from scaling alongside your application's evolution.
Break down your testing activities into the different steps of the Software Testing Life Cycle (STLC). During the planning process, define clear test objectives and establish a comprehensive test strategy. For each step, ask yourself:
Decompose test execution into five distinct steps and apply the same critical questions:
Factor the test execution assessment criteria into your overall test execution strategy. Track and review key deliverables including executed test cases, defect logs, and reports to ensure all criteria are met. Discuss each criterion thoroughly — even if your decision is ultimately to "ignore" certain aspects, make that choice deliberately.
Ensure these key roles participate in your strategy discussions:
The order of involvement may vary based on your organization's structure and project needs.
