Test automation services
Accelerate feedback without creating a brittle test estate. CACI designs, builds and improves scalable automation that expands coverage, reduces repetitive effort and supports faster, more reliable software releases.
Test automation services built for long-term value
Automated tests should give delivery teams fast, dependable evidence. Too often, they become slow, flaky or expensive to maintain because organisations start with tools and scripts rather than strategy, architecture and ownership.
CACI’s test automation services focus on the tests worth automating and the engineering needed to keep them valuable. We assess your applications, critical journeys, risk profile, release cadence, existing coverage and CI/CD pipelines before defining the right framework and implementation roadmap.
From web, mobile and API testing to regression automation and continuous testing, we build solutions that fit your technology landscape and ways of working. The result is earlier feedback, more consistent coverage and greater confidence to release at pace.
Our test automation services
Our test automation services
Identify what to automate, what to retain as manual testing and where investment will deliver the strongest return. We define priorities, target coverage, architecture, tooling, governance, skills and a phased roadmap aligned with delivery goals.
Test architecture and framework engineering
Design and build reusable, scalable test automation frameworks suited to your applications and engineering ecosystem. We focus on clear structure, maintainability, portability, reporting and the ability to evolve as products change.
Automated functional and regression testing
Automate repeatable functional, smoke, sanity and regression tests across critical business journeys. This protects existing behaviour as new features are introduced and enables faster, more consistent validation across releases.
API and integration test automation
Validate APIs, services, contracts, data flows and system integrations earlier and more efficiently. API-level automation can provide fast, stable feedback and expose issues before they surface through end-to-end user journeys.
CI/CD and continuous testing
Embed automated checks within continuous integration and continuous delivery pipelines. We help define quality gates, execution stages, feedback, reporting and failure handling so tests support delivery rather than becoming a disconnected final step.
Automation audit and optimisation
Assess an existing framework, suite or pipeline to identify gaps, duplication, instability and maintenance overhead. We provide prioritised recommendations and can refactor tests, improve coverage and establish sustainable ownership and continuous improvement.
Automate according to risk and return
The aim is not to automate every test. Effective automation targets stable, repeatable and business-critical scenarios where faster execution and consistent evidence justify the cost of building and maintaining the suite.
We consider the frequency of execution, likelihood and impact of failure, stability of the feature, complexity of data and environments, time currently spent on manual testing, and value of earlier feedback. Exploratory testing, usability assessment and rapidly changing features may remain better suited to skilled human testers.
This risk-and-return approach helps avoid low-value scripts, control maintenance overhead and ensure automation remains aligned with the outcomes your delivery teams need.
Test automation across your application landscape
Our engineers can create automation across different layers of the test pyramid and across modern delivery environments.
Web application testing
Automate critical user journeys, cross-browser behaviour and end-to-end workflows across responsive web applications and digital services.
Mobile application testing
Validate repeatable workflows across mobile devices, operating systems and application versions while retaining human testing for experience and device-specific behaviour where needed.
API and service testing
Test endpoints, payloads, contracts, authentication, error handling and data flows directly for fast, focused feedback below the user-interface layer.
Enterprise platform testing
Automate high-value workflows across integrated business applications, back-office platforms and complex data exchanges without losing sight of end-to-end outcomes.
Cloud-native application testing
Support rapid delivery across distributed systems, microservices and containerised environments with automation designed for changing infrastructure and frequent deployment.

FAQs
Answers to common questions about test automation services.
Test automation services help organisations plan, design, build, integrate and maintain automated tests for software applications and systems. They can include automation strategy, tool selection, framework engineering, script development, regression automation, API testing, CI/CD integration, reporting and ongoing optimisation.
The strongest services focus on business risk and maintainability rather than simply producing a high number of scripts. The objective is to create fast, dependable feedback, reduce repetitive manual effort and improve release confidence without building an expensive or brittle automation estate.
Automated software testing uses code, scripts and specialist tools to execute tests, compare actual results with expected outcomes and report failures with limited manual intervention. Tests may validate user interfaces, APIs, integrations, business rules, data or system behaviour.
Automation is particularly valuable for checks that are stable, repeatable, time-consuming and run frequently. It complements rather than replaces manual testing: skilled testers are still important for exploration, usability, new functionality and situations where human judgement is essential.
Good candidates include stable regression tests, smoke and sanity checks, API and contract tests, high-volume data combinations, cross-browser checks and critical workflows that must be validated frequently. Tests within CI/CD pipelines are also strong candidates when rapid feedback can prevent defective changes progressing.
Automation is less suitable when functionality changes constantly, tests run rarely, setup is disproportionately complex or subjective judgement is central. CACI assesses frequency, stability, risk, effort and expected return before prioritising an automation backlog.
A test automation framework is the structured foundation used to create, execute, maintain and report automated tests. It normally defines architecture, coding conventions, reusable components, test data handling, environment configuration, logging, reporting and integration with development and delivery tools.
A well-designed framework makes tests easier to understand, scale and maintain. A poorly designed one can lead to duplication, flaky results and rising support costs. The right framework depends on the application architecture, team skills, delivery pipeline, test types and long-term ownership model.
Tool selection depends on the application, technology stack, existing delivery ecosystem, team capability and tests being automated. Common options include Playwright, Cypress and Selenium for web testing; Appium for mobile; Postman, REST Assured and Pact for APIs; and CI/CD platforms such as Azure DevOps, GitHub Actions, GitLab CI and Jenkins.
CACI takes a tool-agnostic approach. We assess technical fit, integration, skills, maintainability, licensing and total cost of ownership before recommending whether to retain, improve or replace existing tooling.
Automated tests can be triggered at appropriate stages of a continuous integration and continuous delivery pipeline, such as on a code commit, pull request, build, deployment to a test environment or scheduled regression run. Results are returned quickly so teams can investigate failures and prevent unsuitable changes progressing.
Effective integration requires more than adding a test command. Teams need stable environments and data, sensible execution stages, reliable tests, clear quality gates, actionable reporting and agreed ownership when a test fails.
Test automation can shorten feedback and regression cycles, increase the frequency and consistency of repeatable checks, expand coverage across data and configurations, and reduce manual effort. When integrated into CI/CD, it can identify defects closer to the change and support more frequent releases.
Benefits depend on selecting appropriate tests and maintaining the suite. Automating unstable or low-value scenarios can increase cost without improving quality. Success should therefore be measured through useful coverage, execution time, reliability, escaped defects, maintenance effort and delivery outcomes—not script count alone.
Timescales depend on application complexity, existing test assets, environment and data readiness, framework requirements, integration needs and the initial automation scope. A focused proof of value for selected critical journeys may take several weeks; broader regression automation across complex systems is normally delivered incrementally over multiple releases.
CACI prioritises the highest-value scenarios first, establishes the framework and pipeline foundations, and expands coverage in phases. This allows teams to realise useful feedback earlier while learning and improving the approach before scaling.
Costs vary according to discovery and strategy needs, application architecture, number of platforms and environments, framework complexity, volume and type of tests, CI/CD integration, data requirements and ongoing maintenance. Improving an existing framework may require less initial investment than creating one, although significant instability can change that calculation.
CACI assesses both implementation cost and total cost of ownership. The business case should consider manual effort avoided, execution frequency, earlier defect detection, release acceleration, framework maintenance and the operational cost of escaped defects.
Test automation return on investment is measured by comparing the cost of designing, building, running and maintaining automation with the value it creates. Relevant measures can include manual execution time avoided, regression duration, execution frequency, earlier defect detection, coverage of critical risks, release lead time and reduction in escaped defects.
ROI should be assessed over an appropriate period because automation requires upfront investment and continued maintenance. CACI also tracks reliability and maintenance effort: a large suite that frequently fails for non-product reasons may show activity without delivering trustworthy evidence or real value.
Yes. CACI can audit an existing framework, test suite and CI/CD integration to identify gaps in architecture, coverage, reliability, data, environments, reporting, governance and ownership. We distinguish product failures from flaky tests and look for duplication, slow execution and high-maintenance patterns.
The resulting improvement plan may include refactoring, removing low-value tests, rebalancing coverage across UI and API layers, improving data and environment control, strengthening reporting, updating tools or establishing clearer engineering standards and responsibilities.
