Understanding tests better

Test Strategy

One of the key decisions is what kinds of tests should be automated and which approach to testing should be used for manual test.

Catch defect as quickly as possible

The V Model of Software Development

Unit Testing

Unit testing can be on little things like methods/functions or bigger things like modules and classes.

Component Testing

Component testing are used for testing packages, individual executables or subsystems.

System Testing

System testing is done at the level of the whole product and can include a range of system sizes:

individual systems or integrated workflows through multiple systems that have to interact.

Ideal Automated Testing Pyramid

Testing goes to fragile

Assembling a Test Pipeline

Continuous Integration

Defect Prevention before Defect Detection

The ultimate goal of any development process is to build the right product of high quality and to build it with minimum waste.

Defect Prevention techniques address how to prevent “error” before it is injected:

• Root Cause Analysis of problem
• Education and training
• Software process maturity and improvement

Defect Detection techniques address how to find the faults:

• Testing
• Reviews and inspection
• Formal verification
