Types of Manual Testing We Perform

Comprehensive manual testing techniques tailored to your software's needs

Smoke Testing

Performed after a build to verify that critical functionality works, before any detailed functional or regression tests run.

  • Post-build check
  • Critical paths
  • Go / no-go

Sanity Testing

Run after a build with minor changes to confirm that bugs are fixed and the changes introduced no further issues.

  • Targeted checks
  • Fix validation
  • Quick feedback

Regression Testing

Confirms that a recent program or code change has not adversely affected existing features.

  • Existing features
  • Every release
  • Risk-based

Retesting

Testing a bug again to ensure the code is fixed. If it is not, the defect is re-opened; if it is, it is closed.

  • Defect verification
  • Re-open or close
  • Traceable

Functional Testing

We test your web application across combinations of operating system, browser and device for smooth functionality.

  • Web apps
  • Cross-browser
  • Cross-device

Exploratory Testing

Testers design and run tests at the same time, without scripts, using intuition and domain knowledge to uncover unexpected defects.

  • Unscripted
  • Domain knowledge
  • Edge cases

Black Box Testing

Testing the application from the outside, based on requirements and user behavior rather than internal code.

  • Requirements-based
  • User view
  • No code access

White and Grey Box Testing

Techniques that use knowledge of the internal structure, fully or partly, to design more targeted test cases.

  • Code-aware
  • Targeted cases
  • Deeper coverage

Built for Real Business Problems

Real engagements, real outcomes. Every result below comes from a documented client case study.

Why Manual Testing Still Matters

Manual testing is mandatory for every newly developed application before automated testing. Automation does not replicate the minds of humans, and humans are the ones who use your software.

The user's perspective

Test cases are executed the way an end user would use the software.

Visible and hidden defects

Finds the gap between expected and actual output that scripts can miss.

Near-complete coverage

Test cases are planned to cover almost all of the application.

No tooling required

Needs manual testing skill, not knowledge of any automation tool.

Confidence before release

Great effort that gives you assurance of bug-free software.

Manual or Automated Testing?

Most products need both. Here is how we would think about it.

Which testing approach to consider for common needs
If you need... Consider...
A brand-new product tested for the first time Manual testing
Feedback on usability and user experience Manual and exploratory testing
The same checks repeated on every build Automation testing
Quick confirmation that a build is stable Smoke and sanity testing
Confidence that a change broke nothing Regression testing, manual and automated
Both speed and depth of coverage A hybrid manual and automation strategy
