White box testing tests the internal structure and coding of software. It focuses on checking predefined inputs against expected outputs. Popular white box testing techniques include statement coverage, loop testing, path testing, and branch testing. Statement coverage aims to execute all statements in a method. Loop testing checks for exceptions in loops and causes loops to execute in different ways. Path testing aims to cover all paths in the code by constructing logic flow charts. Branch testing, also known as conditional testing, ensures each possible outcome of a condition is tested at least once.

White Box Testing V0.2
White box testing involves testing the internal structure and logic of a program. It includes techniques like statement coverage, loop testing, path testing, and branch testing to ensure all statements, paths, and conditional branches are executed. Grey box testing takes a partial view of internal structures and combines white and black box testing approaches. It may use internal program components like SQL queries to help test functionality without fully understanding the underlying code.
Introduction to White box testing
White box testing is a software testing technique that tests internal coding and infrastructure. It involves writing test cases that exercise the paths in the code to help identify missing logic or errors. The document discusses various white box testing techniques like statement coverage, decision coverage, loop coverage, condition coverage, and path coverage. It also discusses performing white box testing at the unit, integration, and system levels. The session will cover white box testing at the unit level using control flow analysis techniques like building control flow graphs and analyzing possible paths.

black-box-1.pdf
Black box testing techniques like equivalence partitioning and boundary value analysis help reduce the large number of potential test cases when testing without knowledge of internal implementation. Equivalence partitioning divides test cases into equivalence classes where members of a class are expected to behave the same. Boundary value analysis tests values at the boundaries of classes where errors are more likely. Together these techniques help select a relatively small number of representative test cases to derive full external functionality coverage during black box testing.
CPP09 - Testing
This is an introductory lecture on C++, suitable for first year computing students or those doing a conversion masters degree at postgraduate level.
Dynamic Testing
Dynamic testing analyzes the dynamic behavior of code by executing it with different inputs and checking the outputs. There are two main types: black box testing which tests functionality without viewing internal structure, and white box testing which tests based on internal structure. Black box techniques include boundary value analysis, equivalence partitioning, error guessing, cause-effect graphing, and state transition testing. White box techniques include code coverage and complexity analysis. Dynamic testing can find errors not detected through static analysis but takes more time than static testing.

Testing in Python: doctest and unittest (Updated)
The document discusses testing in Python. It defines testing vs debugging, and explains why testing is important even for professional programmers. It provides examples of manually testing a square area function that initially had a bug, and how the bug was detected and fixed. It then introduces doctest and unittest as systematic ways to test in Python, providing examples of using each. Finally, it discusses test-driven development as a software development method where tests are defined before writing code.
Software testing: an introduction - 2017
Software testing involves dynamically verifying that a program behaves as expected on a finite set of test cases. This is done because exhaustively testing every possible case is not feasible. Unit testing involves testing individual program units such as classes through automated tests that make assertions about the output. JUnit is a unit testing framework for Java that uses annotations to identify test methods and make assertions about the results.

It covers topics such as unit testing, integration testing, equivalence partitioning, boundary value analysis, and fault-based versus scenario-based testing. The overall goal is to uncover errors in classes, class collaboration, and subsystem communication through different levels of testing.
Unit Testing a Primer
Unit test ???? - is an automated piece of code that invokes a unit of work in the system and then checks a single assumption about the behavior of that unit of work. This presentation is all about Unit Testing. Will be beneficial to both the developers and testers to learn from.
Software testing
The document discusses various software testing strategies and concepts. It covers the goals of testing as verification (building the software right) and validation (building the right software). It also discusses different types of testing such as black box testing (based on inputs and outputs) and white box testing (based on code). Other topics covered include levels of testing (unit, integration, system), test measures, and a software testing plan.
Building unit tests correctly
This document discusses best practices for writing unit tests. It emphasizes that unit tests should be easy to understand, trustworthy, and robust. A good unit test only fails if a bug is introduced or requirements change. The document provides examples of well-written unit tests and discusses how to avoid common problems like fragile tests. It stresses the importance of testing only specified functionality, using isolation frameworks to mock dependencies, and not putting test logic in the test. Overall, the document promotes writing "clean tests" to avoid brittle tests and minimize maintenance overhead.
Shift-Left Testing: QA in a DevOps World by David Laulusa
Shift-left testing involves injecting quality earlier in the software development process through techniques like unit testing, test-driven development, and regression testing. The presentation discusses principles for effective testing including equivalence partitioning, boundary value analysis, and combinatorial testing. It emphasizes the importance of collaboration between testers and developers through practices like dependency injection and test automation.
Unit Testing with JUnit4 by Ravikiran Janardhana
Unit testing with JUnit allows testing individual units of code, especially methods. JUnit provides annotations like @Test to mark test methods and assert methods to validate results. Tests can initialize objects and environment with @Before, validate outputs with assertEquals and other assert methods, and clean up with @After. Multiple test classes can be run together as a test suite with the @RunWith and @SuiteClasses annotations. JUnit is useful for finding bugs, ensuring code works as intended, and allowing test-driven development.

It also covers white box testing techniques like control flow testing and data flow testing. The key benefits of testing mentioned are that automated testing is faster than manual testing and regression testing has little cost.
Class9_SW_Testing_Strategies.pdf
The document discusses various software testing strategies and techniques. It begins by explaining the importance of testing software before customers use it in order to reduce errors. It then describes different testing techniques including white-box testing, which tests the internal logic and paths of a program, and black-box testing, which tests the inputs and outputs against requirements without considering internal logic. The document provides examples of specific strategies like branch coverage, basis path testing, and boundary value analysis. It also discusses test case documentation and different testing phases from unit to integration to system testing.
Software testing definition
Unit testing focuses on testing individual units or components of an application, such as functions, classes, or modules, to determine if they are fit for use. Integration testing checks how software components function when combined together and interact with each other. White box testing involves testing based on the internal structure and design of the code, such as checking all paths through the code have been executed. Black box testing ignores the internal implementation and tests the functionality of the system from an outside user perspective.

Additionally, the document provides guidance on how to set up breakpoints for debugging, a fundamental aspect of the debugging process which allows the developer to stop the execution of their code at certain points and inspect their program at those stages.
Finally, the document concludes by providing a link to a reference blog. This blog offers additional information and guidance on configuring the remote Python interpreter in PyCharm, providing the reader with a well-rounded understanding of the process.
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Redefining brain tumor segmentation: a cutting-edge convolutional neural netw...
Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

- 2. White Box Testing The box testing approach of software testing consists of black box testing and white box testing. We are discussing here white box testing which also known as glass box is testing, structural testing, clear box testing, open box testing and transparent box testing. It tests internal coding and infrastructure of a software focus on checking of predefined inputs against expected and desired outputs..
- 3. m Testing the internal structure of the software Understand the code and the code will set you free! White-box testing is testing that takes into account the internal mechanis of a system or component It’s also known as Structural testing, clear box testing and glass box testing What is it? © ThoughtWorks, 2007
- 4. Popular Techniques Of Testing • Statement coverage • Loop testing • Path testing • Branch testing
- 5. Statement Coverage © ThoughtWorks, 2007 • 100% method coverage: All methods in all classes are called. • 100% statement coverage: All statements in a method are executed. void foo (int a, b, c, d, e) { if (a == 0) { return; } int x = 0; if ((a==b) OR ((c==d) AND bug(a) )) { x =1; e = 1/x; } }
- 6. Loop testing • Test the ‘for’ and ‘while’ loops in the code. • Look for exceptions of infinite loop. • Cause execution of loop to be skipped. • Loop to be executed exactly once. • Loop to be executed more than once
- 7. Path testing • Make sure all the paths are covered. • Determine the paths • Construct a logic flow chart
- 8. Path testing: Logic flow diagram 4 5 8 9 Exit T F 6 7 T F Start 1 F 2 T 3
- 9. Branch testing Also known as Conditional Testing Make sure that each possible outcome from a condition is tested at least once. if (i=true) printf (“I am true”) else printf (“I am false”) Possible Testcases are 1. i=true; 2. i=false
- 10. Grey box testing What is it? – Mixture of both black box and white box. – Test the system with a basic outlook of internals. When you do? – Once the functionality is developed Example – Database testing – Using SQL
