This document discusses various aspects of software project management and testing. It covers topics like verification and validation, white box and black box testing, unit testing and integration testing. It also discusses testing for web applications, interfaces, security and usability. Parallel testing is discussed as a method to ensure consistency between new and previous software versions.

Software Project Management Are we delivering right things
Why Testing is required • Delivered results should match with expected results • Testing strategy must include – Test Planning – Test Case Design – Test Execution – Resultant Data Collection http://www.radiantminds.co.in
Verification & Validation • Verification – It is set of tasks that ensures that software correctly implements specific functions – “Are we building the product right” • Validation – It is set of tasks that ensures that the S/w that has been built is traceable to customer requirements – “Are we building the right product” http://www.radiantminds.co.in
V & V activities • Technical Reviews • Quality & Configuration audits • Performance monitoring • Documentation Reviews • Database Reviews • Algorithm Analysis • Usability Testing • Acceptance Testing • Installation Testing etc… http://www.radiantminds.co.in
White Box Testing • Developer is suppose to carry out this testing in which – All independent paths have been exercised at least once – Exercise all logical decisions – Executes all loops and boundaries – Exercise Internal Data structures – Condition Testing, Data Flow Testing, Loop Testing http://www.radiantminds.co.in
Black Box Testing • It focuses more on functional requirements of the software. Generally carried out by testers or Business Analysts – Requires domain knowledge – Data volume, System users – Various combination of data and its effect on the system http://www.radiantminds.co.in
V process model Feasibility Study Review User User Requirements Acceptance System System Design Testing Program Program Design Testing Coding
Testing for Conventional S/w • Unit Testing – It applies to the smallest unit of S/w design like component or a module. – Module interfaces are tested – Information flow is tested – Data structures are tested – All control structures are exercised – Boundary conditions are tested – Error handling paths are tested http://www.radiantminds.co.in
Testing for Conventional S/w • Integration Testing – Putting and executing modules together – Data can be lost across an interface – One component has adverse effect on another – Combining sub functions – Variables and Memory management – Database and file design (Find out what is Top-down integration testing and Bottom-up integration testing) http://www.radiantminds.co.in
Testing for Conventional S/w • Regression Testing - Whenever there are any changes software needs to be tested again and again. If the changes are frequent then the efforts spent are much more. • Generally automation is done in these cases. http://www.radiantminds.co.in
Testing for Conventional S/w • Smoke Testing –It is an Integration testing approach, designed as a pacing mechanism for time critical projects. • Focus is more on testing critical functionality and not whole system. http://www.radiantminds.co.in
Alpha & Beta Testing • It is very difficult for S/w developer to foresee how the end customer will really use a program. • Alpha Test – Conducted by end-user at developer’s site. Developer is present during the testing. These tests are conducted in controlled environment. Developer records all the problems encountered http://www.radiantminds.co.in
Alpha & Best Testing • Beta Testing – It is conducted at one or more users site. Developer is not present during testing. The environment is not controlled by the developer. It is like pre-live run. Customer records all the problems what is customer acceptance testing ? http://www.radiantminds.co.in
System Testing • Recovery Testing – Recovery from faults and resume processing with little or no down time • Security Testing – Protection from hackers, Un- happy Employees • Stress Testing – Increasing load on the system by Users, Data, Executing complex data calculations http://www.radiantminds.co.in
System Testing • Performance Testing - To confirm whether the performance requirements are met • Deployment Testing – Execution of software on variety of platforms and under more than one OS. It is also called as Configuration Testing. http://www.radiantminds.co.in
Testing Web Applications • Why it is complex ? • Dynamic UI • Navigation • Performance • Compatibility • Interoperability (Interface with other applications) • Security http://www.radiantminds.co.in
Testing Web Applications • Hardware – CPU, Memory, Storage • OS – Linux, Mac, Windows, Mobile based OS • Browser – Firefox, Safari, IE, Chrome, Opera • UI Components – Active X, Java applets • Plug-ins – Quick Time, Real Player • Connectivity – Cable, WiFi, Modem http://www.radiantminds.co.in
Testing Interface • Links • Forms • Client-side scripting • Dynamic HTML • Pop-up windows • Streaming Contents • Cookies http://www.radiantminds.co.in
Usability Tests • Layout (easily finding required func.) • Readability • Interactivity (menus, buttons etc) • Aesthetics (Color, font, etc) • Display Characteristics (Use of screen size, Resolution etc..) • Personalization • Accessibility (for disable persons) http://www.radiantminds.co.in
Security Testing • Firewall • Authentication (Validation of clients and servers) • Encryption • Authorization Find out what is Vulnerability Testing? What is Spoofing ? Difference Between Load & Stress Testing? http://www.radiantminds.co.in
Parallel Testing - Why • To ensure that the processing of new application (new version) is consistent with respect to the processing of previous application version. • Demonstrate consistency and inconsistency between 2 versions of the application. http://www.radiantminds.co.in
Parallel Testing - How • Same input data should be run through 2 versions of same application system • Parallel testing can be done with whole system or part of system (module) • Verification is done through acceptance Testing & Stress Testing http://www.radiantminds.co.in
Parallel Testing - When • When there is uncertainty regarding correctness of processing of new application where the new and old version are similar. • Application of new patches • Change in Technology • Major application changes • Change in OS http://www.radiantminds.co.in
