Test automation tools matched to your coverage
We help QA leads and engineering directors select complementary test automation tools for their product. We define coverage layers, browser and device requirements, CI execution and maintenance ownership, then route each decision to the engineering work it needs.
01Capabilities
QA automation from cases to execution
We choose QA tools within the coverage and delivery scope agreed through our QA and test automation practice. The suite design determines how the tools work together.
Regression suites built from written cases
We document the checks and expected results before implementing them. Prioritized regression cases give the suite a readable purpose and connect each automated check to the behavior it protects.
Layering across unit, API and browser checks
We place checks at the layer that exercises the behavior directly. Service and API coverage sits below browser journeys on transactional systems of the kind in our fintech work, with browser checks reserved for interface-specific behavior.
Browser and device coverage based on traffic
We build the target matrix from product traffic and journey risk, then verify execution support through a platform such as BrowserStack. For e-commerce interfaces, the matrix reflects the browser and device combinations customers use.
Repeatability diagnosis and suite repair
We measure intermittent failures, inspect synchronization, selectors and shared data, then repair the causes while retaining useful coverage. A quality audit provides an independent assessment when that is the starting point you need.
02Stack
Four test automation tools with distinct roles
Browser suites, API checks and native-app tests have different automation and execution requirements. The directory separates web tools, JVM coordination and the platform used to run the selected checks.
| Tool | What that means in practice |
|---|---|
| Selenium | Browser automationSelenium WebDriver drives browsers through the W3C WebDriver protocol. Choose the required browser, version and operating-system combinations, then design the suite and execution setup around their supported configuration.Selenium automationOr book a meeting |
| BrowserStack | Remote executionA testing platform supplying supported browser/device execution. Verify web versus native-app requirements separately, along with the relevant product, framework, available targets and concurrency plan. Compare subscription and operating responsibilities against the coverage needed.Device and browser coverageOr book a meeting |
| TestCafe | JavaScript suitesA JavaScript and TypeScript web test runner. Assess the suite's coverage, installed version and browser requirements. Its native and proxy browser automation modes depend on the version and target browser.TestCafe automationOr book a meeting |
| TestNG | Java coordinationCoordinates JVM test groups, lifecycle, data-driven cases, reporting and parallel execution. Check Java, runner and build compatibility alongside the suite design, for new and existing systems.TestNG for Java suitesOr book a meeting |
03Fit
Match the testing requirement to the tool and layer
We compare tools against the actual browser/device matrix, runtime and coverage already in place. Migration effort, operating cost and maintenance ownership enter the same decision.
| Your situation | What we recommend |
|---|---|
| A new JavaScript or TypeScript browser suite needs Chrome and Safari | Compare web toolsCompare Playwright, Selenium and TestCafe against the browser matrix and debugging needs. Playwright's WebKit is distinct from branded Safari; verify the required browser, version and operating-system support. |
| A required real-browser matrix includes Safari and Edge | Verify browsersSelenium provides WebDriver browser automation. Confirm the exact browser, version and operating-system combinations, then choose the runner and local or remote execution needed for that matrix. |
| A Java product and build that your engineers already maintain | Coordinate JavaSelenium supplies browser actions; TestNG coordinates test execution and lifecycle. Keep the runner, test data and reporting integrated with the Java build, with the versions checked together. |
| A new Java suite or a planned runtime/runner upgrade | Compare runnersCompare the proposed JUnit Platform/Jupiter version with TestNG against Java runtime and build-plugin support. Assess the grouping, data handling, parallel scope and reports the suite needs. |
| The coverage matrix needs additional devices, system versions or browsers | Plan executionBrowserStack or an equivalent platform can supply supported browser and device combinations. Check framework compatibility, concurrency, access requirements and plan cost against the matrix; compare self-hosting with the same operating scope. |
| An existing suite has intermittent failures and a framework change is proposed | Measure firstRun repeated checks against an unchanged build, then inspect waits, selectors, shared data and execution conditions. Use the findings and the value of retained coverage to choose targeted repair or a scoped migration. |
Scope
We define the agreed suite design, coverage layering and maintenance ownership, with automated and manual responsibilities recorded for your team. Tool selection includes the cost of operating the suite and the work needed to change it. unicrew has ISTQB-certified QA engineers. Our information-security and quality management systems are ISO 27001:2022 and ISO 9001:2015 certified, audited by Quay Audit UK.

Establish repeatability, layering and suite ownership
We assess suite repeatability first, then define the isolation, coverage layers and failure ownership needed for the agreed change.
- Measure repeatability on an unchanged buildRun the suite repeatedly against an unchanged build and record which tests produce different results. Keep the failure conditions and frequency with that baseline so the repair priorities follow observations.
- Use condition-based waits and isolated dataReplace fixed-duration waits with the conditions each check needs. Give tests independent accounts or records, with setup and cleanup that keep concurrent runs from changing one another's starting state.
- Place checks at the appropriate layerDecide which behavior belongs at the unit, service/API or browser layer. Retain browser checks for interface journeys and use lower-level checks where they exercise the behavior directly.
- Assign ownership to unstable checksQuarantine known unstable checks with a named owner and repair deadline. Keep failure reports visible and document which checks remain release gates, so the pipeline has a clear action when a test fails.
05Case studies
TestCafe automation and a Test Cases System for real estate
We match the tool to your browser list, your devices and the language your team writes. Trust in the results comes from a layered suite, repeatable tests and a named owner. We put those three in place, whichever tool runs the suite.

Questions about test automation tools and ownership
Yes. We scope QA automation engineering around the suite, coverage layers and maintenance responsibilities you need.
Our managed teams include delivery coordination; QA and test automation covers a scoped automation outcome.
We compare the actual browser requirements, team toolchain and maintenance needs before selecting the web test framework.
Selenium supplies WebDriver browser automation. TestCafe runs JavaScript and TypeScript web suites with native or proxy browser automation selected for the installed version and target browser. Playwright supports multiple browser engines, but its WebKit build is distinct from branded Safari.
We automate stable, repeated checks with defined expected results, starting from release regression and the service/API layer.
Human judgment and rapidly changing screens remain explicit parts of the full-cycle testing scope. The plan records what is automated, what stays manual and when that allocation is reviewed.
Assess the existing suite before choosing repair or replacement.
We measure repeatability against an unchanged build, then examine waits, selectors, shared data and execution conditions. The recommendation weighs retained coverage, compatibility and migration effort, so the change addresses an observed cause.
We start with a scoping call about your suite, tool decisions and next coverage requirement.
Provide repository access and recent build results, or the product journeys to cover when no suite exists. We return written priorities for tool selection, coverage layers and manual scope. Engineering work is quoted against that scope. Most engagements start within two to four weeks.
