Study Notes
Intro To Software Testing
- Introduction to software testing overview
Agenda
- The presentation will cover:
- Software definition
- Testing and software testing
- Importance of testing why
- Bugs and bug finding
- Software error types
- Testing specifications
- Types of software testing in engineering
- Testing levels
- Testing methodology
- SDLC and STLC
- V model
What is Software?
- Software is computer programs plus associated documentation
Documentation Types
- User Documentation is a documentation type
- Technical Documentation is a documentation type
- Marketing Documentation is a documentation type
What is Software Testing
- Software testing checks if the software product meets expected requirements
- The checks ensure the software product is defect free
Why Testing is Important?
- Testing is important to find and correct defects
- Testing is important to check if the user’s needs are satisfied
- Testing avoids users detecting problems
- Testing provides quality products
Objectives of Testing
- Ensure customer requirements are met
- Define defects
- Prevent defects
- Ensure best quality
- Generate high quality test cases
Why Bugs Occur in Software?
- Bugs occur due to miscommunication or lack of communication, leading to unclear application behavior
- Time pressure contributes to bugs
- Programming mistakes lead to bugs
- Changing requirements introduce bugs
Common Misunderstandings About Software Testing
- Testing is not just debugging
- Testing is still key even if programmers are much more careful
- Testing isn't reserved as an activity after coding is complete
- Testing is never complete or ends
- Testing is a creative process
What is a Bug?
- A bug is a deviation of the actual result from the expected result
Types of Errors in Software
- Error: A human action producing an incorrect result that leads to a fault
- Bug: The presence of an error at the time the software is being used
- Fault: A state of software caused by an error
- Failure: Deviation of the software from its expected result and is an event
Software Testing Specifications
- Specifications of the code is to have the script prompt the user to type in "what animal do you like more: frog or cat?"
- If the user types either frog or cat, the output on screen will say "frog / cat is a great animal"
- If nothing is entered in the prompt from the user, the output on the screen will display "You did not type anything"
- If any other words are types, it will display on the screen "You did not enter the expected words"
Software Free Error
- Testers must ensure the software works as expected and is error free
- There is a probability that bugs will be missed by testers
- Testing cannot cover 100% of software operation possibilities
Types of SW Testing
- Functional Testing
- Non-Functional Testing
- Maintenance Testing
Types of SW Testing in SW Engineering
- Functional Testing entails unit, integration, and UAT testing
- Non-Functional Testing entails performance, usability, and scalability
- Maintenance Testing entails regression and maintenance
Level of Testing
- Acceptance Testing
- System Testing
- Integration Testing
- Unit Testing
Testing Methodology
- Black box testing does not require knowledge of internal program design; tests are based on requirements and functionality
- White box testing requires knowledge of the internal program design and code, and tests are based on code coverage
Black Box Testing
- Applied for functional and non functional testing, without reference to the internal structure of the system
Black Box Testing Techniques
- Equivalence Partitioning (EP):
- If VALUE is between 1 and 100, then the output is ‘Pass’
- Boundary value analysis(BVA):
- Applicable for numeric fields and date
- 6 Test cases
Decision Table Testing
- Used to test system behavior for different input combinations
- The decision table is a tabular representation of inputs versus rules, cases and test conditions
State Transition Testing
- Outputs are triggered by changes to the input conditions
- It is designed to execute valid and invalid state transitions
White Box Testing
- Testing based on analysis of the internal structure of the component
- Goal is to verify all the decision branches, loops, and statements in the code
- Statement Coverage
- Branch Coverage
- Path Coverage
Test Cases Objectives
- Test to pass(Happy scenario)
- Assures that the software minimally works
- Applies simple and straightforward test cases
- Test to fail(Bad scenario)
- Choose test cases to appear the weaknesses in software
- Designing test cases with the sole purpose of breaking the software
Software Deployment Cycle
- The software development cycle is developer -> software tester - > Deployment
SDLC and STLC
- SDLC (Software Development Life Cycle): A sequence of activities carried out by Developers to design and develop high-quality software
- STLC (Software Testing Life Cycle): A series of activities carried out by Testers methodologically to test the software product
V Model
- A development process where execution of processes happens in a sequential manner in a V-shape
