Automated testing has become very important. It strengthens the continuous testing cycle by reducing human involvement and minimizing errors. Test scripts, scalable and reliable test infrastructure, and efficient test data generation are the key building blocks of automated testing, which are crucial in ensuring software quality.

However, asynchronous progression, a common feature in automation testing, particularly during end-to-end testing, must provide complete visibility into the continuous testing cycle. This lack of visibility is a significant challenge, with 78% of businesses citing it as their biggest hurdle in continuous testing.

Test orchestration – a testing framework that offers unmatched insight and comprehensive visibility into the continuous testing process. If DevOps were a coin, test automation, and test orchestration would be its two sides, working together to deliver software continuously and efficiently.

Test orchestration enables grouping and distributing automated tests intelligently across runner environments, ensuring the continuous integration pipeline functions smoothly. By utilizing test orchestration, teams can achieve scalability, efficiency, and comprehensive visibility into their testing processes, unlocking the true potential of continuous delivery.

In this article, we will explore test orchestration in Playwright.

What is Test Orchestration?

Test orchestration refers to automating a sequence of testing tasks and scheduling them to run in a specific linear order. It allows you to execute your various test cases and scripts one after the other, giving you control over deciding the optimal sequence.

Test orchestration is often considered one of the core building blocks of comprehensive automated testing. The primary purpose is to optimize and coordinate your overall testing strategy holistically and organizationally.

With test orchestration, you gain valuable insight into the big-picture view of your software’s testing and deployment process. This transparency helps foster collaboration as your team can easily understand, plan, and modify the testing approach as needed.

Additionally, orchestration provides the flexibility to repeatedly test an entire application or certain critical features at multiple points during development. This enables detecting and fixing bugs or issues as they occur rather than waiting until the end.

In an orchestrated test environment, you can automatically run through a full suite of automated test cases as a coordinated workflow or pipeline. The orchestration engine intelligently schedules and executes the various testing jobs, scripts, and processes properly across your environments.

For example, you may want to first run static code analysis tools to check for syntax and styling issues. Once that passes, you can kick off unit tests to validate each individual code module. If those are clear, you move on to integration tests covering the interactions between components. Finally, you run end-to-end UI tests simulating real user scenarios.

Test orchestration tools allow you to define this precise order of operations and control the workflow. They can spin up temporary test environments on demand, execute the corresponding test suite, capture the results, tear down after completion, and seamlessly transition to the next stage.

This level of coordination is critical for complex applications tested across multiple platforms, browsers, devices, configurations, and conditions. Orchestration maximizes efficient utilization of testing resources and computes capacity through parallel execution when possible.

Ultimately, the key value of test orchestration is coordinating all the different testing tasks and processes into one cohesive automated pipeline with full visibility. It elevates automated testing from disparate scripts to an overarching continuous testing strategy aligned with your development lifecycle.

What are the Key Components of an Effective Test Orchestration System?

Test orchestration acts as the conductor, coordinating all the different automated testing activities into one seamless workflow. But behind the scenes, several critical components work together to make an orchestration system effective.

Optimized Continuous Delivery Pipeline

At the core is a super-optimized continuous delivery (CD) pipeline that automatically deploys code updates to production environments without manual steps. Before releasing software changes, developers use CD to automatically run a comprehensive suite of tests to validate all aspects of the new code – APIs, user interfaces, etc.

The code flows through an automated continuous integration pipeline, gets versioned in a repository once tests pass, and can then be pushed live through the CD pipeline. An end-to-end test orchestration solution requires seamless testing integration into a single ecosystem supporting 100% automated delivery.

Adaptive Test Scripts

Maintaining updated test scripts for all your automated test cases is a huge burden, especially for large projects. Whenever functionality changes, associated test cases likely need updates, too. Finding impacted scripts, modifying them, and reverifying them is tedious and error-prone.

In an orchestrated pipeline, the test scripts themselves must be able to adapt automatically to any changes in functionality, tooling, or UI. The goal is a tight, comprehensive orchestration of test execution flows.

Real-Time Test Data Generation

Creating valid and realistic test data presents a significant challenge in automated testing. Test scripts expect data to be in a certain state to run properly. For example, during end-to-end testing, multiple test scenarios may need to access and modify the same data simultaneously, impacting each other’s results.

An effective data generation technique can deliver properly masked, compliant test data on-demand for each scenario, allowing tests to run independently with customized data every time. This eliminates dependencies and distortions.

Automated Code Resilience

While most companies have automation testing tools, only 15% of test cases are actually automated on average. Well-implemented automation increases code resilience – if a release fails to test, the code base can quickly revert to a prior stable version.

This allows completing tests faster, covering more scenarios, identifying more issues, and accelerating feedback loops. Continuous automated testing drives greater code resilience.

Continuous Monitoring

Continuous monitoring continuously checks for risks, issues, and deviations throughout the software development lifecycle. It provides visibility into application uptime, security, performance, and logs – understanding the real-world health and execution quality of the software.

An uninterrupted stream of monitoring data with built-in validation rules allows for the immediate detection of problems. This continuous automated monitoring is critical for maintaining an optimized, self-healing test orchestration pipeline.

Best Practices for Effective Test Orchestration

Managing tests well is key to getting the most benefits and ensuring smooth, streamlined testing processes. Here are some best practices to follow:

• Automate as Much as Possible: Manually running tests or managing workflows can be time-consuming and lead to errors. Set up scripts, pipelines, and tools that automatically execute tests, generate reports, and provision resources.

• Prioritize Which Tests to Run: Not all tests are equally important. Some are more critical than others, and prioritizing which ones to run first ensures the most important functions are validated upfront. Organize your tests based on risk, complexity, or business impact and manage them accordingly.

• Run Tests in Parallel: Modern tools let you run tests simultaneously across multiple environments, browsers, or devices. Parallel execution can significantly reduce testing time, enabling faster feedback and quicker delivery. However, to avoid conflicts, be mindful of resource limits and dependencies.

• Monitor and Report: Effective test management requires comprehensive monitoring and reporting. Monitor test execution in real time and collect detailed reports on results, performance metrics, and code coverage. This information helps identify bottlenecks, optimize resources, and improve testing strategies.

• Maintain Test Environments: Test management often involves running tests across multiple environments like development, staging, and production. Ensure these environments are consistently configured and maintained to avoid environment-specific issues and ensure reliable test results.

• Collaborate Closely: Test management is a collaborative effort involving developers, testers, and operations teams. Foster open communication and knowledge sharing so everyone understands the processes, test requirements, and their roles.

Following these practices unlocks the full potential of test orchestration, streamlining your testing processes and delivering high-quality software more efficiently.
