csharp repitition structures
This document is a lesson on repetition structures (loops) in C# for beginners. It introduces while, for, and do-while loops. The while loop executes a block of code as long as a condition is true. The for loop is preferred when the number of iterations is known. The do-while loop checks the condition after executing the statements, so the body is executed at least once. Examples are provided for each loop type. The document ends with assignments for students to write looping programs.
Looping
The document discusses various looping constructs in C++ including while, do-while, and for loops. It provides examples of using counters, sentinels, nested loops, break, continue, and running totals with loops. Key points covered include the differences between pretest and posttest loops, using loops for input validation, and tips for writing good test data when testing programs.
Loops in C Programming Language
Importance of loops in any programming language is immense, they allow us to reduce the number of lines in a code, making our code more readable and efficient.

Types of loops in c language
The document discusses the different types of loops in C language: while loop, do-while loop, and for loop. It provides the syntax and an example of each loop. The while loop checks the condition first and repeats the block of code as long as the condition is true. The do-while loop ensures the block of code executes at least once before checking the condition. The for loop allows initialization of a counter, specifies a condition to test, and how to change the counter between iterations of the loop.
Different loops in C
This presentation discusses different loops in C programming. It defines programming and structured programming. It then explains the three types of loops in C - for, while, and do/while loops. Sample programs are provided to demonstrate each loop, showing how they iterate and check their loop conditions. The for loop checks at the top of the loop. The while and do/while loops can check at the top or bottom of the loop respectively.
Looping statements in Java
The document discusses looping statements in Java, including while, do-while, and for loops. It provides the syntax for each loop and explains their logic and flow. While and for loops check a condition before each iteration of the loop body. Do-while loops check the condition after executing the body at least once. Nested loops run the inner loop fully for each iteration of the outer loop. Infinite loops occur if the condition is never made false, causing the program to run indefinitely.
Control statements
The document discusses the flow of control in programs and control statements. There are two major categories of control statements: loops and decisions. Loops cause a section of code to repeat, while decisions cause jumps in the program flow depending on calculations or conditions. Common loop statements are for, while, and do-while loops. Common decision statements include if-else and switch statements. Nested statements and loops can also be used to further control program flow.
Loops in c
There are two main types of loops in C - entry control loops and exit control loops. Entry control loops like for and while loops check the loop condition at entry, while exit control loops like do-while check the condition at exit. For loops use initialization, condition, and update statements. While loops continuously check a condition. Do-while loops execute the body at least once before checking the condition. Loops can be nested, with one loop inside another. This allows looping of statements within another loop.
Loops in c
The document discusses different types of loops in C programming: for loops, while loops, and do-while loops. For loops allow initialization of a variable, specify a condition, and how to increment the variable. While loops repeatedly execute code as long as a condition is true. Do-while loops are similar but check the condition at the bottom of the loop, so the code executes at least once. Examples of each loop type are provided.
Reconciling Functional Programming and Exceptions
This document discusses reconciling functional programming with exceptions in Scala. It presents two approaches for handling exceptions: wrapping existing exceptions using Scala's Try type or returning error types instead of throwing exceptions. The preferred solution is to return a Try type that contains either the successful result or captured exception. The document also covers chaining operations, avoiding foreach, and alternative types like Either and \/ for representing errors.
Control structure C++
The document discusses various control structures used in programming, including sequence, repetition (loops), and selection (branching). It covers common loop and conditional statements like while, for, if/else, switch/case. Control structures allow programs to execute instructions in different orders depending on conditions or to repeat steps multiple times. Keywords like break and continue change the normal flow of loops.
Jumping statements
The document discusses three types of jumping statements in C language: break, continue, and goto.
1) The break statement terminates the nearest enclosing loop or switch statement and transfers execution to the statement following the terminated statement.
2) The continue statement skips the rest of the current loop iteration and transfers control to the loop check.
3) The goto statement unconditionally transfers control to the labeled statement. It is useful for branching within nested loops when a break statement cannot exit properly.

It also covers switch statement for selecting one of multiple code blocks to execute and jump statements like break, continue and goto. Examples are provided for if, foreach, while, switch, break and goto statements.
C++ chapter 4
The document discusses different control structures in C++ programs including sequence, selection, and repetition. It defines each structure and provides examples. Sequence refers to executing statements in order. Selection (branching) executes different statements depending on conditions. Repetition (looping) repeats statements while conditions are met. Common control structures in C++ include if/else statements, switch statements, and various loops like while, for, and do-while loops. The document provides details on the syntax and flow of each structure.

The document provides syntax and examples to explain how each of these statement types work.
Understand Decision structures in c++ (cplusplus)
The document discusses different conditional statements in C++ including if statements, if-else statements, and nested if statements. It explains the syntax and logic of each statement. The if statement executes a block of code if a condition is true. The if-else statement executes one block if the condition is true and another block if it is false. Nested if statements allow placing if statements inside other if statements to check multiple conditions. Logical and relational operators are used to build conditions.

C++ loop
The document discusses different types of loops in C++ including while, do-while, for, and switch-case statements. It provides examples of using each loop or statement to repeat operations a certain number of times or while a condition is met. Key examples include a countdown loop using while, calculating factorials with for, and a calculator program using switch-case to perform math operations.
escape sequences and substitution markers
This document discusses escape sequences, verbatim strings, and substitution markers in C#. It provides examples of using escape sequences like \n for newlines. Verbatim strings prefixed with @ disable escape sequences. Substitution markers like {0} in a format string are replaced with variable values. The document demonstrates various string formatting techniques and taking user input in C# programs.

Test driven development
Test Driven Development (TDD) is a process where developers write automated tests before developing code. It follows a short cycle: 1) Write a failing test, 2) Develop minimum code to pass the test, 3) Refactor code. An example tests multiplication of dollars, initially failing but passing after adding Dollar class with times() method. Tests are then improved to avoid side effects and assert equality. A Franc class is similarly developed until a common Money superclass is created to DRY code and allow cross-type comparisons.
SE2_Lec 21_ TDD and Junit
Test-driven development (TDD) is a software development process where test cases are written before code is produced. The process involves writing a failing test case, producing the minimum amount of code to pass the test, and refactoring the new code. TDD encourages writing automated tests that can be repeatedly executed after small code changes to ensure all tests continue to pass.

Test Driven Development
Test-Driven Development (TDD) is a software development approach or method in which test cases are developed to specify and validate what the code will do.
The main ideas are -
1. Test cases for each individual function are created.
2. The newly created test cases are run for obvious fail at the very beginning.
3. Then the new code is developed in order to pass the test cases.
4. Make the code simple and bug-free.
5. Avoid duplicate codes for a single functionality.
How TDD works:
1. Add a new test to the test suite.
2. (Red) Run all the tests to ensure the new test fails.
3. (Green) Write just enough code to get that single test to pass.
4. Run all tests.
5. (Refactor) Improve the initial code while keeping the tests green
6. Repeat.
There are two levels of TDD –
1. Acceptance TDD (ATDD) and
2. Developer TDD

SE2018_Lec 20_ Test-Driven Development (TDD)
The document discusses test-driven development (TDD) and unit testing. It explains that TDD follows a cycle of writing an initial failing test case, producing just enough code to pass that test, and refactoring the code. Unit testing involves writing test cases for individual classes or functions, using assertions to validate expected outcomes. The JUnit framework is introduced for writing and running unit tests in Java.
Test Driven Development
The document introduces Test Driven Development (TDD). TDD is a software development process that relies on short development cycles where you write an automated test first, then code to pass that test, and refactor as needed. The key benefits of TDD are that it encourages simple design, validates correctness, and drives the design of a program in a modular way. TDD best practices include writing self-explanatory test assertions, keeping tests small and isolated, integrating code frequently, and following the TDD mantra and rhythm of red-green-refactor.
IntroTestMore
This document provides an overview of Perl testing with Test::Simple and Test::More. It discusses why testing is important, basic tests with ok(), and more advanced matching functions like is(), like(), and can_ok() provided by Test::More. It also covers controlling test flow using skip(), todo(), diag(), pass(), and fail(). The goal is to introduce Perl testing and help readers feel comfortable writing and using tests.

Tdd
TDD introduces NUnit for writing tests before production code. It requires failing tests first, then just enough code to pass each test. NUnit attributes define tests, fixtures, and assertions. Tests for bank accounts that hold balances and transfer funds demonstrate a TDD process of repeatedly writing a failing test, then minimum code to pass it.
Tdd
TDD introduces the concepts of test-driven development and using NUnit for testing. It outlines the basic steps of TDD: write a failing test first, then just enough code to make it pass, and repeat. Key aspects of NUnit are attributes like [TestFixture] and [Test] to mark classes and methods, and assert methods to validate logic. An example walks through creating a simple test for an account class with a balance that can be set and verified.
Bdd for-dso-1227123516572504-8
This document provides an overview of test-driven development (TDD) and behavior-driven development (BDD), beginning with common misconceptions about TDD and how it differs from traditional testing approaches. It discusses how TDD is a design activity that focuses on emergent design and driving design with tests. Key principles of TDD/BDD are explained, such as writing tests before code, the red-green-refactor cycle, and outside-in development. The document also covers test automation, mock objects, different testing tools and frameworks, and best practices for TDD/BDD.
Test Presentation
The document discusses the benefits of testing code through test-driven development and continuous integration. It explains that testing allows developers to have confidence that code will work as intended and catch any unintended behaviors. Test-driven development involves writing tests before code to validate outcomes, and continuous integration runs test suites frequently to ensure new code stays compatible. Conditionals require thorough testing of all possible code paths to ensure robust code. Shared development relies on testing to verify any new changes don't break existing features.
Tdd for BT E2E test community
Test-driven development (TDD) is a software development process where developers first write automated tests that define desired improvements or new functions. They then write code to pass those tests and refactor the new code to acceptable standards. TDD involves writing unit tests, integration tests, and acceptance tests using tools like JUnit, FitNesse, and Cucumber. Practicing TDD can provide benefits like improved code quality, reduced bugs, and increased developer productivity.
TDD in PHP - Memphis PHP 2011-08-25
The document is a presentation about test-driven development (TDD) in PHP. It introduces TDD and the speaker, defines the TDD process, lists benefits and drawbacks, and demonstrates a live coding example of using TDD to build a calculator and tutor class. The example shows writing tests first, then code to pass the tests, and refactoring with confidence due to the tests. The goals are to provide a practical TDD example and demonstrate how TDD impacts design decisions.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

TDD in Powershell
- 2. About Following concept from https://laracasts.com/series/code-katas-in-php/episodes/2 This following is an except from a class presentation.
- 3. Test-Driven Development 1. Write a test case for some code that has yet to be implemented 2. Run the test case to verify it, which fails 3. Write only as much code as necessary to make the test pass 4. Run the test case
- 4. Roman Numeral Calculator 1 => I; Write the test; Watch it fail.
- 5. Simplest implementation to make it pass Returning “I” brings us to “Green”
- 6. 2 => II; Write Test; Watch it Fail
- 7. Strategies Two simple ways to make this pass. We chose to use the second method.
- 8. 5 => V; Write Test; Watch it Fail.
- 10. Add VI => 6 to Tests; Watch it fail
- 11. Refactoring to use a $solution variable.
- 12. Testing after Refactor; 6 still fails.
- 13. Remove the Else statement. Still Failing tests for 5 & 6.
- 14. Add minimal code to make test pass.
- 15. X => 10; Write Test; Watch it Fail.
- 16. Code duplication pattern becoming apparent
- 17. Write Test for 11=>XI Test is already passing; Move on to next edge case.
- 18. 20 => XX; Write Test; Watch it Fail.
- 19. Changing “if” to “while” lets this logic run twice for 20 making the test pass.
- 20. 50 => L; Write Test; Watch it Fail.
- 21. Duplicate code shows us that we may have room for refactoring.
- 22. 4 => IV; Write Test; Watch it Fail.
- 23. Make 4 Pass
- 24. Test for 9 is added. After 9 Fails we duplicate the code from 10 and change it to make 9 pass.
- 25. Refactor to pattern Other if statements will also pass using a while statement.
- 26. Refactor (cont.) The Statement can be refactored to use a while loop as well.
- 27. Refactor Duplicate code removed by using a lookup hashtable. Test by removing the: while “$Number -ge 50 loop.” Tests still Green!
- 28. Remove >= 10 Loop; Fail since Lookup missing X.
- 29. Add 10 = “X” to lookup; Back to Green.
- 30. Remove all other while loops; Add Values to lookup. Why is L Failing?
- 31. Hashtables are not sorted.
- 34. Back to Green!
- 36. Community Help Team integration apps can help with on the fly code review / testing.
- 37. Almost forgot the sunflower
