# What is BVA in testing with example?

## What is BVA in testing with example?

Boundary Value Analysis (BVA) is a Black-Box testing technique used to check the errors at the boundaries of an input domain. The name comes from the Boundary, which means the limits of an area. So, BVA mainly focuses on testing both valid and invalid input parameters for a given range of a software component.

## What is BVA and ECP?

BVA stands for BOUNDARY VALUE ANALYSIS & ECP stands for EQUIVALENCE CLASS PARTITIONING ECP:- In it we divide the whole class into different modules we can say makes small parts of that to make testing convienient. lets assume the class can take values from 1-100 then we can divide it in 10 sub modules 1-10,10-20 etc.

What do you mean by Boundary value analysis give two examples of boundary value testing?

Example #1: Suppose, a printer has to make and deliver printed copies ranging from 1 to 150. So, to apply boundary value testing, the analysis is done on the boundaries, taking the extreme ends. The maximum value is 150 and the minimum value is 1. The invalid values in this test case will be 0 and 151.

### How do you write a test case using boundary value analysis?

Write Test Cases for Valid partition value, Invalid partition value and exact boundary value.

1. Test Cases 1: Consider password length less than 8.
2. Test Cases 2: Consider password of length exactly 8.
3. Test Cases 3: Consider password of length between 9 and 11.
4. Test Cases 4: Consider password of length exactly 12.

### What are the 7 principles of testing?

The seven principles of testing

• Testing shows the presence of defects, not their absence.
• Exhaustive testing is impossible.
• Early testing saves time and money.
• Defects cluster together.
• Beware of the pesticide paradox.
• Testing is context dependent.
• Absence-of-errors is a fallacy.

What are the types of boundary value analysis?

Two techniques – Boundary value analysis and equivalence partitioning testing techniques are used. In Equivalence Partitioning, first, you divide a set of test condition into a partition that can be considered. In Boundary Value Analysis you then test boundaries between equivalence partitions.

## What are the types of boundary value testing?

Normal Boundary Value Testing.

• Robust Boundary Value Testing.
• Worst-case Boundary Value Testing.
• Robust Worst-case Boundary Value Testing.
• ## What is difference between BVA and equivalence partitioning?

BVA considers the input data values from the defined boundaries. Equivalence Partitioning examines input data values from the range of equivalence class intervals.

What is RTM in testing?

Definition: Requirements Traceability Matrix (RTM) is a document used to ensure that the requirements defined for a system are linked at every point during the verification process. It also ensures that they are duly tested with respect to test parameters and protocols.

### What are the 5 basic principles of testing?

5 Key principles of software testing for every developer

• Testing should show the presence of defects. Every application or product release should be tested by different teams and passed through different phases of testing.
• Early testing.
• Exhaustive testing.
• Testing is context-dependent.
• Defect clustering.

### Which testing is best?

Manual Testing vs. Automated Testing

Aspect of Testing Manual
Test Execution Done manually by QA testers
Test Efficiency Time-consuming and less efficient
Test Coverage Difficult to ensure sufficient test coverage

What is Boundary value analysis?

Boundary-value analysis is a software testing technique in which tests are designed to include representatives of boundary values in a range. The idea comes from the boundary. Given that we have a set of test vectors to test the system, a topology can be defined on that set.

## What are the limitations of boundary value analysis?

Disadvantages of BVA. The disadvantages of the BVA method are as follows. It cannot test all test case input values. BVA technique is not suitable with Boolean Variable, because Boolean is a type of data which have values of 1 and 0.

## Which is better boundary value or Equivalence Partitioning?

Boundary Value Analysis is better than Equivalence Partitioning as it considers both positive and negative values along with maximum and minimum value. So, when compared with Equivalence Partitioning, Boundary Value Analysis proves to be a better choice in assuring the quality.

Why is boundary value testing important?

Boundary value analysis is one of the widely used case design technique for black box testing. It is used to test boundary values because the input values near the boundary have higher chances of error.

### What are the 3 types of requirements traceability?

There are three types of RTM: forward traceability, backward traceability, and bidirectional traceability.

### Who prepares RTM in testing?

The test engineer will prepare RTM for their respective assign modules, and then it will be sent to the Test Lead. The Test Lead will go repository to check whether the Test Case is there or not and finally Test Lead consolidate and prepare one necessary RTM document.

What are the 7 principle of testing?

## What are the four common types of testing?

There are four main stages of testing that need to be completed before a program can be cleared for use: unit testing, integration testing, system testing, and acceptance testing.

## Which automation tool is best?

Know About The Best Automation Testing Tools for 2022

• Selenium.
• Appium.

Where you can use Boundary value analysis?

### How do you calculate boundary value?

Boundary Value Analysis is based on testing the boundary values of valid and invalid partitions.

Valid Test cases: Valid test cases for the above can be any value entered greater than 17 and less than 57.

1. Enter the value- 18.
2. Enter the value- 19.
3. Enter the value- 37.
4. Enter the value- 55.
5. Enter the value- 56.
