Introduction

What Is Test Case?

Testing is a process centered around the goal of

finding defects in a system

Test case:Set of input valuesSet of expected resultsHow to execute the test and check

resultsExpected post-conditions

What Is test case optimization?

Typically applies to unit test cases where coverage

approaches 100%

Implies ordering execution such that: Rate of fault detection is increased Amount of time to perform

regression is reduced Elimination of unnecessary test cases during regression

runs

6

Why Is Test Case Optimization Important?

Execution complexity Elapsed time to execute Computing resources Wait time for test completion Late defect detection and correction

7

Who Develops Test Cases?

Developers Dedicated quality assurance staff Automated test generation techniques

Software Development Life Cycle (SDLC)

 SDLC stands for Software Development Life Cycle. It is a process that describes how to develop, design and maintain the software project ensuring that all the functional & user requirement, goals and objective are met. For the creation of innovative software products the development life cycle undergoes different phases.

• Requirement Analysis phase.• Design phase.• Coding or Development phase.• Testing phase.

QualityQuality means “conformance to requirements”

The best testers can only catch defects that are contrary to specification.

Testing does not make the software perfect.

If an organization does not have good requirements engineering practices then it will be very hard to deliver software that fills the users’ needs, because the product team does not really know what those needs are.

12

Test AutomationTest automation is a practice in which testers employ a software tool to reduce or eliminate repetitive tasks.

Testers either write scripts or use record-and-playback to capture user interactions with the software being tested.

This can save the testers a lot of time if many iterations of testing will be required.

It costs a lot to develop and maintain automated test suites, so it is generally not worth developing them for tests that will executed only a few times.

Example

13

Test Requirements Identified (among others): “Validate that you can insert an entry”

“Validate that insertion fails if entry already present”

“Validate that insertion fails if table already full”

“Validate that you can insert an entry to an empty table (initial)”

conclusion

Increased the rate of early fault detection and

correction

Find bugs early so they can be corrected early

Regression test only those areas that have changed

Reduce the amount of time to execute full unit regression test suites
