Regression Tests
================
.. _regression-tests:


**SVM**

Several HAP specific tests do various checks on different datasets included in 
the test file name (e.g., test_svm_wfc3ir.py). These are only run when the 
`bigdata <https://ci-watson.readthedocs.io/en/latest/bigdata.html>`_ mark is 
specified since they require retrieval of significant data from MAST. The four 
groups of tests used are as follows:

The four groups of tests used are as follows:

A. Simple tests:
   
    test_svm_samewcs
     * Checks that products for both detectors are aligned to the same catalog.

    test_svm_wcs
     * Checks the output primary WCSNAME includes FIT_SVM_GAIA.

    test_svm_manifest_name
     * Ensures the manifest file is created.

   This also includes the general success of SVM alignment and catalog creation code.


B. SVM catalog tests (currently disabled)
    
    test_svm_point_total_cat
     * Tests the number of sources in the point source catalog compared to expected value. 
    
    test_svm_segment_total_cat
     * Tests the number of sources in the segmentation source catalog compared to expected value. 


C. Tests for different detectors
    
    test_svm_wcs_ir, test_svm_wcs_ir_all, test_svm_wcs_uvis, test_svm_wcs_uvis_all
     * SVM alignment and catalog creation for different detectors.


D. Mean magnitude tests

    test_svm_point_cat_meanmag, test_svm_segment_cat_meanmag: 
     * Checks that catalog mean magnitudes are within 0.5% of previous values.
