Software Testing Fundamentals
Software Testing FundamentalsChankey Pathak This document provides an overview of software testing concepts and processes. It discusses the importance of testing in the software development lifecycle and defines key terms like errors, bugs, faults, and failures. It also describes different types of testing like unit testing, integration testing, system testing, and acceptance testing. Finally, it covers quality assurance and quality control processes and how bugs are managed throughout their lifecycle.
Principles of Software testing
Principles of Software testingMd Mamunur Rashid The document outlines seven principles of software testing: 1) Testing shows the presence of errors, not their absence; 2) Exhaustive testing of all possible test cases is impossible; 3) Testing early in the development cycle is important to more easily fix defects; 4) Defects tend to cluster together, following an 80-20 distribution; 5) Test effectiveness fades over time as software changes; 6) Testing methods depend on the type of application; 7) Finding no errors does not mean the system is usable - user requirements must still be met.

Regression testing
Regression testingMohua Amin Regression testing is testing performed after changes to a system to detect whether new errors were introduced or old bugs have reappeared. It should be done after changes to requirements, new features added, defect fixes, or performance improvements. There are various strategies for regression testing including re-running all tests, test selection, test prioritization, and focusing on areas like frequently failing tests or recently changed code. While regression testing helps ensure system quality, managing large test suites over time poses challenges in minimizing tests while achieving coverage. Automating regression testing can help address these challenges.

Software testing.pptKomal Garg Software testing is the process of evaluation a software item to detect differences between given input and expected output. Also to assess the feature of A software item. Testing assesses the quality of the product. Software testing is a process that should be done during the development process. In other words software testing is a verification and validation process.
Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include, but are not limited to the process of executing a program or application with the intent of finding software bugs (errors or other defects).
Software testing can be stated as the process of validating and verifying that a computer program/application/product:
• meets the requirements that guided its design and development,
• works as expected,
• can be implemented with the same characteristics,
• and satisfies the needs of stakeholders.
Software Development Process Cycle:-
PLAN (P): Device a plan. Define your objective and determine the strategy and supporting methods required to achieve that objective.
DO (D): Execute the plan. Create the conditions and perform the necessary training to execute the plan.

8.flip flops and registers
8.flip flops and registersDeepak Sharma Flip flops are basic memory elements that store one bit of information as a 1 or 0. Common types include RS, D, JK, T, and master-slave JK flip flops. Flip flops have two stable states and two complementary outputs. They are used as registers for storage, in frequency dividers, and digital counters. Registers consist of groups of flip flops that hold information, while shift registers can shift data in one or both directions using cascaded flip flops and clock pulses. Flip flops have applications in interfacing digital systems, as delay circuits, and for converting between serial and parallel data.

Repaint() requests a repaint but does not guarantee it. Example code demonstrates basic graphics methods and includes an applet example with supporting HTML. Advantages of applets include cross-platform capability and security sandboxing, while disadvantages are needing the Java plugin and slower initial startup.
9.cs instrset
9.cs instrsetDeepak Sharma This document discusses computer instruction sets. It defines an instruction set as the complete collection of instructions understood by a CPU in either binary machine language or symbolic assembly language. An instruction typically contains an operation code and references to operands and results. There are different types of instructions for tasks like data transfer, arithmetic, logic, and control flow. Instructions can be classified as zero-address, one-address, two-address, three-address, or four-address depending on the number of operands. Complex instruction set computers have many generalized instructions while reduced instruction set computers have fewer simpler instructions that can execute faster.
5.interface and packages
5.interface and packagesDeepak Sharma This document discusses interfaces and packages in Java. It defines an interface as a reference type that can contain only constants, method signatures, and nested types, with no method bodies. Interfaces are used to define common behaviors for unrelated classes. The document also defines packages as logical groupings of related classes and interfaces, and discusses how to create user-defined packages and control access to classes using access modifiers like public, private, and protected.
10.data transmission
10.data transmissionDeepak Sharma This document discusses different modes of data transmission between digital devices. It describes parallel transmission, which transfers all data bits simultaneously over separate lines and is faster but more costly than serial transmission. Serial transmission sends each data bit in sequence over a single line, making it less costly but slower. Transmission can be synchronous, sending multiple bytes at once without start/stop bits, or asynchronous, sending one byte at a time with start/stop bits. Modes of transmission include simplex (one-way), half duplex (one-way at a time), and full duplex (two-way simultaneous).
7.error management and exception handling
7.error management and exception handlingDeepak Sharma This document discusses error handling in Java programs. It defines two types of errors: compile-time errors and runtime errors. It also discusses exceptions, the different exception classes (Exception, RuntimeException, Error), and checked and unchecked exceptions. Finally, it provides details on how to implement exception handling using try, catch, and finally blocks, including their syntax and flow. It provides an example of a program with a division by zero error and how exception handling can prevent the program from crashing.
4.software management
4.software managementDeepak Sharma This document discusses software project management. It states that managing software projects through their entire life cycle, from initial planning through monitoring and termination, is necessary to deliver high-quality products on time. The document outlines the key aspects of software project management, including project planning, monitoring and control, quality management, maintenance, and the overall processes involved. It provides details on planning, monitoring, quality assurance, quality control, maintenance activities and models.

3.software testing
- 1. SOFTWARE TESTING BCA 5th Sem DEEPAK SHARMA 12KSSB6031
- 2. INTRODUCTION It is the process used to identify the correctness, completeness and quality of developed computer software. It is the process of executing a program/application under positive and negative conditions by manual or automated means. It checks for the : - Specification Functionality Performance
- 3. SOFTWARE TESTING PRINCIPLES: All tests should be traceable to customer requirements. Testing should be planned long before testing stage begins . Testing by third party will be very effective. All tests should be traceable to customer requirements. Testing should begin “in the small” and progress towards testing “in the large”.
- 4. Module Testing Unit Testing Sub System System Testing Acceptance Testing TEST PROCESS
- 5. TESTING METHODOLOGIES Black box testing White box testing
- 6. Black box testing No knowledge of internal program design or code required. Tests are based on requirements and functionality. White box testing Knowledge of the internal program design and code required. Tests are based on coverage of code statements, branches, paths, conditions.
- 7. TESTING LEVELS Unit testing Integration testing System testing
- 8. UNIT TESTING Tests each module individually. Follows a white box testing (Logic of the program). Done by developers.
- 9. INTEGRATION TESTING Once all the modules have been unit tested, integration testing is performed. It is systematic testing. Produce tests to identify errors associated with interfacing. Types: Big Bang Integration testing Top Down Integration testing Bottom Up Integration testing Mixed Integration testing
- 10. SYSTEM TESTING The system as a whole is tested to uncover requirement errors. Verifies that all system elements work properly and that overall system function and performance has been achieved. Types: Alpha Testing Beta Testing Acceptance Testing Performance Testing
- 11. ALPHA TESTING It is carried out by the test team within the developing organization . BETA TESTING It is performed by a selected group of friendly costumer. ACCEPTANCE TESTING It is performed by the customer to determine whether to accept or reject the delivery of the system. PERFORMANCE TESTING It is carried out to check whether the system meets the nonfunctional requirements identified in the SRS document.
