- At its core, data-driven testing is a sophisticated form of automated testing. Unlike traditional testing, where a single test scenario is executed, data-driven testing employs a systematic approach of running multiple iterations of a test. The defining feature is the variation in input data with each test run.

Jan 10, 2024 · Data-Driven Testing is a type of software testing methodology or more exactly approach to the architecture of automated tests by creating test scripts and reading data from data files. In this type, the data files involved are Data pools, CSV files, Excel files, ADO objects, ODBC sources, etc.
Sep 22, 2023 · The keyword-driven testing is based upon a keyword-driven framework that defines functional automation testing and is categorized into four different parts test steps for test cases, objects, actions, and data sets.

You can use the Microsoft unit test framework (MSTest) for managed code to set up a unit test method to retrieve values from a data source. The method is run successively for each row in the data source, which makes it easy to test a variety of input by using a single method.
inline data using the DataRow attribute
member data using the DynamicData attribute
from some well-known source provider using the DataSource attribute
As an example, let's assume that you have:
A solution called MyBank that accepts and processes transactions for different types of accounts.
A project in MyBank called BankDb that manages the transactions for accounts.
A class called Maths in the BankDb project that performs the mathematical functions to ensure that any transaction is advantageous to the bank.
A unit test project called BankDbTests to test the behavior of the BankDb component.
A unit test class called MathsTests to verify the behavior of the Maths class.
For inline tests, MSTest uses DataRow to specify values used by the data-driven test. The test in this example runs successively for each data row.
[DataRow(1, 1, 2)]
[DataRow(2, 2, 4)]
[DataRow(3, 3, 6)]
[DataRow(0, 0, 1)] // The test run with this row fails public void AddIntegers_FromDataRowTest(int x, int y, int expected)
var target = new Maths();

Jul 12, 2024 · Process of BDD : Write the behavior of the application. Write the automated scripts. Then Implement the functional code. Check if the behavior is successful and if it not successful then fix it. Organize the code (Optional) Repeat the steps for another behavior. What is Test Driven Development (TDD)?
Apr 30, 2024 · Data driven testing allows testers to input a single test script that can execute tests for all test data from a table and expect the test output in the same table. It is also called table-driven testing or parameterized testing.
Data-driven or parameterized testing is a way to automate the creation, use, and management of (virtually unlimited) pools of test input data. This guide covers everything you need to know to implement data-driven testing in your existing or brand-new test automation practices. Try codeless Data-Driven Testing for free. Topics.
Jun 18, 2024 · Data-driven testing is a software testing methodology in which test data is stored in external data sources (such as databases, spreadsheets, or XML files) and used to drive test cases and test scripts. This approach separates the test logic from the test data, allowing for the creation of reusable and maintainable test cases.
