   Test Case Design

Learning Objectives

You will learn about:
•   Dynamic testing of Software Applications
•   White box and black box testing
•   Various techniques used in White box testing
•   Various techniques used in black box testing
•   Static program analysis
•   Automation of testing process

Introduction

Software
can be tested either by running the programs and verifying each step of
its execution against expected results or by statically examining the
code or the document against its stated requirement or objective. In
general, software testing can be divided into two categories, viz.
Static and dynamic testing. Static testing is a non-execution-based
testing and carried through by mostly human effort. In static testing,
we test, design, code or any document through inspection, walkthroughs
and reviews as discussed in Chapter 2.  Many studies show that the
single most cost-effective defect reduction process is the classic
structural test; the code inspection or walk-through. Code inspection
is like proof reading and developers will be benefited in identifying
the typographical errors, logic errors and deviations in styles and
standards normally followed. 

Dynamic testing is an execution
based testing technique. Program must be executed to find the possible
errors. Here, the program, module or the entire system is executed(run)
and the output is verified against the expected result. Dynamic
execution of tests is based on specifications of the program, code and
methodology.

	< ="Content-" content="text/; charset=utf-8">< name="ProgId" content="Word.">< name="Generator" content="Microsoft Word 12">< name="Originator" content="Microsoft Word 12"><> In software Testing Test Design is the important for software testing itself, to reduce the testcases as minimum as possible and find more defects There is a tool called TestersDesk.com which is used specially for Test Design and Test Data Generation Tools, There are different types of tools which are used to reduce the testcases into little number, I can explain clearly with good example PairWise TestCase Generator This tool will be useful in the situations where several parameters exist each of which take several values resulting a high number of Test combinations, to reduce that combinations into a little number we are using this tool. It will cover almost 80-90% of Test coverage. It will cover single fault determination. For Example: Net connections: Tata, Reliance, Airtel Browsers: IE6, IE7, IE8 Platforms: XP, XP2, XP3, Vista Ram: 1GB, 2GB, 3GB Manually if we generate the combinations it will generate 108 pair combinations like 1) Tata-IE6-XP-1GB 2) Reliance-IE7-XP2-2GB etc but our pairwise TestCase Generator Generates into a little number 13 which is very simple for the Tester to test those 13 pair combinations. PairWise Testing can be used mainly when we have to find critical defects.
