black box testing techniques with examples ppt

Black box testing. This method of testing explores paths that are directly accessible from user inputs or external interfaces to the software. Black box testing also known as specification based testing is a software testing type, wherein the testers have no knowledge of the internal structure, design, and code of the software. A black box consist of FDR & CVR . This article defines each of these techniques and describes, with examples, how you can use them together to create better test cases. This video is all about White Box Testing Techniques with Examples . It is a type of testing used to check the functionality of the Application Under Test (AUT). The idea behind this technique is to divide (i.e. To put it in simple terms: Under Black box testing, we test the software from a user’s point of view, but in White box, we see and test the actual code. Black box test design techniques are used to pick the test cases in a systematic manner. As the level goes higher and higher, more becomes the complexity of the box. You will get to know its advantages, disadvantages, uses, working, and full concept. Black and white box testing. We will talk very briefly about white box testing, later in this article. What is black box testing? Software development life cycles are incomplete without software testing. black-box testing concerns itself exclusively with the inputs and outputs of an application, white-box testing enables you to see what is happening inside the application. In a typical case, white box analysis is used to find vulnerable areas, and black box testing is then used to develop working attacks against these areas. ISTQB Definition. There are different types of testing used in industry. It has got many names such as Clear Box Testing or Open Box Testing or Glass Box Testing or Transparent Box Testing or Code-Based Testing or Structural Testing. to partition) a set of test conditions into groups or sets that can be considered the same (i.e. 3.1 Equivalence Parti tion ing . Test cases for the application whose input box accepts numbers between 1-1000. Equivalence partitioning (EP) is a specification-based or black-box technique. Unlike black-box and gray-box testing, white-box penetration testers are able to perform static code analysis, making familiarity with source code analyzers, debuggers and similar tools important for this type of testing. This can be applied to every level of software testing such as Unit, Integration, System, and Acceptance Testing.. Testers create test scenarios/cases based on software requirements and specifications. Focus in this type of testing is to test the functionality of the software and ensure its conformance with the specified requirements. Random input is used to test the system's reliability and performance. Random Testing Characteristics: Random testing is performed where the defects are NOT identified in regular intervals. Black Box Testing Techniques Equivalence Partitioning. system, and there are two major categories of testing techniques, functional and structural. The name itself says that the tester who is going to test the product will give input and examine the output results without having the prior knowledge of source code. Black box testing and White box testing are testing methods used for software testing.Dynamic testing can be black box or white box testing. The selection of test cases for functional testing is based on the requirement or design specification of the software entity under test. White box testing is a testing technique that takes into account the internal mechanism of a system. Black Box Testing is a method of Software Testing also called Behavioral Testing. Functional Testing: the software program or system under test is viewed as a “black box”. Black Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is not known to the tester ; White Box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is known to the tester. Each testing type is having its own advantages & disadvantages. A major White box testing technique is Code Coverage analysis. There are Different Types of White Box testing techniques available to use. The other sibling of the black box testing is white box testing but there is significant difference in both these methods of testing the software. Black box testing or functional testing is a method which is used to examine software functionality without knowing its internal code structure. We carry out this testing without viewing the internal code structure, implementation information, and details of the internal paths of the software - Black Box Testing When it comes to BlackBox testing we only concern ourselves with the requirements and Black box testing techniques and examples. Test managers among you will have, by now, been involved with some level of white box testing throughout your career. Types of Black Box Testing Techniques: Following black box testing techniques are used for testing the software application. Ppt. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.It is sometimes referred to as specification-based testing. What is black box testing? To exercise the statements in the above white box testing example, WhiteBox test cases would be . The login screen has two fields, username and password as an input and the output will be to enable access to the system. Following are some techniques that can be used for designing black box tests. The main function of black box testing is to test the interior design/implementation of an item which cannot be known to the tester. Software Testing can be majorly classified into two categories: . CISS White-box: loop testing • Statement and branchcoveragearenot sufficient • Single loop strategy: • Zero iterations • One iteration • Two iterations • Typical number of iterations • n-1, n, and n+1 iterations (n maximum number of allowable iterations) • Nested loop strategy: • Single loop strategy often intractable • Select minimum values for outer loop(s) Various forms of black box testing techniques. Difference Between White-Box and Black-Box Testing. Black box testing example: A simple login screen of software or a web application will be tested for seamless user login. There are different kinds of testing and it is chosen based on the actual requirements. In Black box testing, we perform testing without seeing the internal system code, but in WBT we do see and test the internal code. Black box Testing Applies to: This method touches upon the following areas of manual testing: 1- Integration, 2- System, and 3- Acceptance. This white box testing example guide teaches you everything you need to know. The testers have no knowledge of how the system or component is structured inside the box. Differences between black box testing and white box testing. Difference between black box testing and white box testing. Black box testing methodology_sans. Black-box testing. Hence, finding the right kind of activity helps you in saving a whole lot of time every day. Software testing plays a major role in ensuring the quality and proper functioning of your software product. You can save time and reduce the number of test cases required to effectively test inputs, outputs, and values. Testers can divide possible inputs into groups or “partitions”, and test only one example input from each group. Test Cases 3: Consider password of length between 9 and 11. Random Testing, also known as monkey testing, is a form of functional black box testing that is performed when there is not enough time to write and execute the tests. It can be applied to all software testing levels but is mostly employed for the higher level acceptance and system related ones. It is also called glass box testing or clear box testing or structural testing. This software testing technique base on the principle that, if a system works well for these particular values then it will work perfectly well for all values which comes between …
