TestIsolation Property

Specifies which changes to the database to roll back after the tests in the test runner codeunit execute.

Applies To

Test runner codeunits. A test runner codeunit has the SubType Property (Codeunit) set to TestRunner.

Property Value

Value	Description
Disabled	Do not roll back any changes to the database. Tests are not isolated from each other. This is the default value.
Codeunit	Roll back all changes to the database after each test codeunit executes.
Function	Roll back all changes to the database after each test function executes.

Remarks

We recommend that you design tests to be independent of each other. Tests might read from and write to the same database, which means that tests can interact with each other. If tests interact, then you may experience incorrect test results. To eliminate test interactions, use the TestIsolation property to roll back changes to the database after each test function or after each test codeunit.

Note

If you specify that you want to roll back database changes, then all database changes are rolled back, including changes that were explicitly committed to the database during the test by using the COMMIT function.
