Software Testing Concepts and Definition Presented by Naseer Ahmad / Prepared by Sikandar Ahmed

Primary purpose of testing is to detect software failures, so that defects may be discovered and corrected.

Items to be covered • Concepts

• SQA vs Testing

• Test Senario vs Test Cases

• Testing Cycle

• Testing Definitions

• Testing Methods

• Testing Levels

• Testing Types

SQA VS Testing

4

Software Quality Assurance

5

• SQA consists of a means of monitoring the software

engineering processes and methods used to ensure quality.

• In SQA, software process specialists and auditors are concerned for the

software development process rather than just the artifacts such as

documentation, code and systems.

• They examine and change the software engineering process itself to

reduce the number of faults that end up in the delivered software

• SQA is the implementation of policies and procedures intended to

prevent defects from occurring in the first place.

Software Testing

• Software testing is a task intended to detect defects in software by

contrasting a computer program's expected results with its actual

results for a given set of inputs.

• Software testing is a part of the software quality assurance (SQA)

process.

6

Test Plan

•A test specification is called a test plan.

•A test plan is a document detailing a systematic approach to testing

a system/software.

•The plan typically contains a detailed understanding of the

eventual workflow.

•There are three major elements that should be described in the test

plan, These are also used in a formal test strategy:

•Test Coverage

•Test Methods

•Test Responsibilities

7

Test Scripts

• A test script is a procedure, or programming code that replicates

user actions.

• Test Case will be a baseline to create test scripts using a tool or a

program.

8

Traceability Matrix

• A traceability matrix is a table that correlates requirements or

design documents to test documents.

• It is used to change tests when related source documents are

changed

• The Purpose to select test cases for execution when planning for

tests by considering requirement coverage.

9

Test Scenario VS Test Case

Test Scenario is “What to be tested”

Test Case is “How to be tested”.

10

Test Scenario

• It is also known as Test Suite or less commonly Validation Suite.

• A test scenario is a collection of test cases that are intended to be

used to test a software program

• Purpose is to show that it has some specified set of behaviors.

• It often contains detailed instructions or goals for each collection of

test cases and information on the system configuration to be used

during testing.

11

Test Case

• A test case is a set of conditions or variables under which a tester

will determine whether an application, software system or one of its

features is working as it was originally established for it to do.

• A test case is usually a single step, or occasionally a sequence of

steps, to test the correct behavior/functionality, features of an

application.

• For a Test case, an expected result or expected outcome is usually

given.

12

Test Data

• In most cases, multiple sets of values or data are used to test the

same functionality of a particular feature.

• All the test values and changeable environmental components are

collected in separate files and stored as test data.

• It is also useful to provide this data to the client and with the

product or a project.

13

Example: Login Feature

Test Scenarios of Login Feature:

1) Verify UI components of the Login screen.

2) Verify functionality of Login.

3) Verify functionality of Keep me logged in.

4) Verify functionality of Forget password.

14

Example: Login Feature (Cont.)

Test Scenario 2: Verify functionality of Login

List of Test Cases:

1) Click on login button with enter valid username and password.

2) Click on login button with enter username only (Password left empty).

3) Click on login button with enter password only (username left empty).

4) Click on login button without username and password (both are empty).

5) Click on login button with enter invalid username and password.

15

Example: Login Feature (Cont.)

Test Case 1: Click on login button with enter the username and password.

Step1: Click in user name text box and enter user name in this field.

Expected Result: It allows to type username.

Step2: Click in password text box and enter password in this field.

Expected Result: It allows to type password and it should not visible to

user.

Step 3: Click on Login button.

Expected Result: System verifies user name and password if both are valid

then user should be logged in successfully.

Basic Testing Cycle

• Requirements Analysis

• Test Planning

• Test Development

• Test Execution

• Test Reporting

• Test Result Analysis

• Defect Retesting

• Regression Testing

• Test Closure
