Why Software Testing is Important


Find bugs

Testing helps identify defects and flaws in the software before release. Without thorough software testing, bugs could go undetected and impact customers in the field. Testing exposes issues early so development teams can fix them.

Ensure quality

Testing improves the overall quality of the software by fixing the found issues. Testing not only finds bugs but verifies key quality attributes like reliability, performance, security, and usability. Comprehensive testing leads to higher quality software.

Save money

Finding issues early in testing saves time and money compared to finding them in production. Fixing bugs during development is cheaper than fixing bugs once released. Less issues in production means fewer patch releases and happier customers.

Ensure functionality

Testing verifies all the features and functionality of the software works correctly as expected under different scenarios. It checks the UI, APIs, integrations, workflows and ensures they function properly end-to-end.

Build confidence

Successful testing across various test types and environments gives confidence that the software works correctly under different conditions. Comprehensive testing leaves no doubts about software readiness.

Meet requirements

Testing checks the software against specified business, functional and technical requirements and validates if it meets them as expected. This ensures alignment with what customers and stakeholders want.

Partnership Model

The Time and Material (T&M) pricing model is an effective approach for small and medium-sized businesses, especially those with complex, long-term projects. It also works well for ongoing testing, bug fixing, maintenance and support efforts. With T&M, scope and budgets are defined iteratively versus upfront payment for the entire project. This provides flexibility to adjust effort and plans as needs change over time.

By scoping and estimating iteratively, T&M pricing can adapt to changing needs. For SMBs, this incremental style matches the way many technology projects unfold. T&M provides an adjustable framework to evolve systems over time.

Key benefits of the T&M approach:

  • Accommodates fluid requirements that emerge during project execution
  • Allows for changes in timeline or resources required
  • Gives client control to pivot priorities as market conditions shift
  • Suits prolonged engagements across multiple phases

Key QA Activities

Quality assurance engineers play a vital role across the software development life cycle. Key QA responsibilities span:

Requirements Gathering

QA reviews specs to ensure testability and begins test planning. Understanding what the software aims to achieve is crucial.

Test Planning

Based on the requirements, QA defines overall test strategy, types of testing needed and creates initial test cases to verify key functionality.

Test Execution

QA executes test cases, analyzes results, logs defects, and may automate repetitive tests. Verifying software behavior is the heart of the QA role.

Bug Tracking

Defects get documented, are then prioritized for developers,and then are re-tested after fixes to check for proper resolution. No issue should slip through the cracks.

Regression Testing

Existing test cases get executed with each software change to catch any new issues introduced. QA assures older functionality remains intact.


Once all tests have passed and priority bugs fixed, QA signs off to release a high quality, thoroughly-validated software version to customers.

How do you create a test script?

Creating robust test automation scripts is a key skill for QA engineers. The key steps include:
