How do you generate test data?

Test Data Generation Approaches:

  1. Manual Test data generation: In this approach, the test data is manually entered by testers as per the test case requirements.
  2. Automated Test Data generation: This is done with the help of data generation tools.
  3. Back-end data injection: This is done through SQL queries.

What is data Generator?

DataGenerator generates data according to some pattern instead of reading data from file, database, or any other data source. To generate data, a generate transformation may be defined. It uses a CTL template for DataGenerator or implements a RecordGenerate interface.

What are data sets?

  2. Enter a name for this data set.
  3. Click Shared to enable the Data Source list.
  4. Select the data source where the Microsoft Excel File resides.

What is the purpose of a dataset?

The purpose of DataSets is to avoid directly communicating with the database using simple SQL statements. The purpose of a DataSet is to act as a cheap local copy of the data you care about so that you do not have to keep on making expensive high-latency calls to the database.

What is the difference between data collection and data generation?
