-## Testing Data
-
-The project contains [a lab class](https://github.com/imsweb/mph/blob/master/src/test/java/lab/TestingDataCreation.java) that can be used to generate CSV files 
-that contains fake data along with the library result.
-
-A sample testing file is available in the project: [mph-testing-2000-2022.csv.gz](https://github.com/imsweb/mph/blob/master/src/test/resources/mph-testing-2000-2022.csv.gz)
-
-To create larger file, clone the project and execute the main method of that class locally.
-
-The class allows the following parameters (defined in the top of the main method):
- - numTests: the number of rows for the generated CSV file
- - minDxYear: the minimum DX year to use
- - maxDxYear: the maximum DX year to use
-
-The CSV files will contain the following columns:
- - year1
- - month1
- - day1
- - site1
- - hist1
- - beh1
- - lat1
- - year2
- - month2
- - day2
- - site2
- - hist2
- - beh2
- - lat2
- - result
- - reason
-
-The lab class uses the [Data Generator](https://github.com/imsweb/data-generator) library to create the fake data.

 ## About SEER
