How does Manual Testing with CodesClue work?

We follow 4 steps: Requirement Analysis and Test Planning; Test Design and Execution; Defect Management and Retesting; Continuous Quality Improvement. You see progress at every milestone and agree each stage before the next one starts.

How long does Manual Testing take?

A focused test cycle for a release takes one to two weeks; setting up automation takes a few weeks; ongoing QA runs alongside your development as long as you need it.

Can you work with our existing systems and team?

Yes. We fit into your tools and process, including Jira, your CI pipeline and your test management system, whether the product was built in-house or by another vendor.

Do you work with startups as well as enterprises?

Yes. We work with startups, growing businesses and established enterprises, with engagement models that fit each stage.

Which technologies do you use for Manual Testing?

We choose tools to fit your environment. Common choices include Selenium, Cypress, Postman, JMeter, JUnit and SonarQube.

Where is your team based?

Our team is based in India, the United States and Germany, which gives you working-hours overlap across Asia, Europe and North America.

How do you price projects?

Three ways, matching our engagement models: a dedicated team billed monthly, staff augmentation where you add individual engineers to your own team, or a fixed-scope project with an agreed timeline and budget. The first consultation is free; we scope your requirements there and quote after it.

How do you handle security and compliance?

Security is built into every engagement: data encrypted in transit and at rest, role-based access control, logging and monitoring, and audit-ready configuration. For regulated industries we design to the relevant standard, for example HIPAA-ready systems for healthcare. We sign an NDA before any engagement, so your systems and data stay confidential from the first conversation.
