Equivalence class testing in software testing pdf
Rather than select any element within an equivalence class, select values at the edge of the equivalence class. For example, given the class: 1 <= input <= 12 you would select values: -1,1,12,13. test all boundary conditions, on both sides.
Equivalence partitions are also known as equivalence classes In order to test the software that calculates the interest due, we can identify the ranges of balance values that earn the different rates of interest. For example, 3% rate of interest is given if the balance in the account is in the range of If the equivalence classes are chosen wisely, the potential redundancy among test cases is greatly reduced. The key point in equivalence class testing is the choice of the
Introduction Use of Equivalence Classes as the basis for functional testing has 2 motivations: Have a sense of complete testing Avoid redundancy
Purpose of this blog is to present information on Software Testing including both Manual and Automation testing. It helps to understand the concepts and provides knowledge to implement the same .
Equivalence Class Testing is appropriate when input data is defined in terms of intervals and sets of discrete values. Equivalence Class Testing is strengthened when combined with Boundary Value Testing Strong equivalence takes the presumption that variables are independent. If that is not the case, redundant test cases may be generated. ECT–31 Guidelines and observations – 2 Complex
6) Equivalence class testing is used when the program function is complex. the complexity of the function can help identify useful equivalence classes. 7) Strong equivalence class testing makes a presumption that the variables are independent and the corresponding multiplication of test cases raises issues of redundancy. . 9) The difference between the strong and weak forms of equivalence

Equivalence Class Testing EC Testing is when you have a number of test items (e.g. values) that you want to test but because of cost (time/money) you do not have time to test them all. Therefore you group the test item into class where all items in each class are suppose to behave exactly the same. to 0, 5% rate of interest is given if the balance in the account is in the range
Equivalence Class Testing-Black Box Software Testing Techniques. The use of equivalence classes as the basis for functional testing and is appropriate in situations like:
Test cases are designed for equivalence data class. The equivalence partitions are frequently derived from the requirements specification for input data that influence the processing of the test object. A use of this method reduces the time necessary for testing software using less and effective test cases.
Using equivalence class partitioning a test value in a particular class is equivalent to a test value of any other member of that class. Therefore, if one test case in a particular equivalence class reveals a defect, all the other test cases based on that class would be expected to reveal the same defect.
Equivalence Partitioning Technique is also known as Equivalence Class Partitioning or ECP. The idea behind this technique is to divide/partition a set of test conditions into groups or sets that can be considered the same or equivalence .This is used to reduce the total number of test cases to a finite set of testable test cases, still covering maximum requirements.
Equivalence partitioning is a Test Case Design Technique to divide the input data of software into different equivalence data classes. Test cases are designed for equivalence data class.

Guidelines for Equivalence Class Testing: The following guidelines are helpful for equivalence class testing 1) The weak forms of equivalence class testing (normal or robust) are not as comprehensive as the corresponding strong forms. 4) Equivalence class testing is approximate when input data is defined in terms of intervals and sets of discrete values. So. This is certainly the case when
E.g. if you divided 1 to 1000 input values invalid data equivalence class, then you can select test case values like 1, 11, 100, 950 etc. Same case for other test cases having invalid data classes. This should be a very basic and simple example to understand the Boundary value analysis and Equivalence partitioning concept.

Equivalence Partitioning is the Black Box Test Case Design Technique. In the Black Box Testing, we are only interested in the implementation issues. The design of the test case is based on how the end user uses the application to carry out his/her activities with the software. Here we design the test case in such a way that it covers the both positive and negative test cases.
