# Test Templates

Test templates are macros for basic test patterns recommended by Distributional. It allows the user to quickly create tests from a builder in the UI. Distributional provides five classes of Test Templates.

* [Single Run](https://docs.dbnl.com/v0.20.x/using-distributional/testing/testing-strategies/test-that-a-given-distribution-has-certain-properties): These are parametric statistics of a column.
* [Similarity of Statistics](https://docs.dbnl.com/v0.20.x/using-distributional/testing/testing-strategies/test-that-distributions-have-the-same-statistics): These test if the absolute difference of a statistic of a column between two runs is less than a threshold.
* [Similarity of Distributions](https://docs.dbnl.com/v0.20.x/using-distributional/testing/testing-strategies/test-that-columns-are-similarly-distributed): These test if the column from two different runs are similarly distributed is using a nonparametric statistic.
* [Similarity of Results](https://docs.dbnl.com/v0.20.x/using-distributional/testing/testing-strategies/test-that-specific-results-have-matching-behavior): These are tests on the row-wise absolute difference of result
* [Difference of Statistics](https://docs.dbnl.com/v0.20.x/using-distributional/testing/testing-strategies/test-that-distributions-are-not-the-same): These tests the signed difference of a statistic of a column between two runs

## Creating Test from Test Templates

From the Test Configuration page, click the Test Template dropdown under My Tests.

Select from one of the five options and click `ADD TEST`. A Test Creation drawer will appear and the user can edit the statistic, column, and assertion that they desire. Note that each Test Template has a limited set of statistics that it supports.
