Class BasicTester

java.lang.Object
  skyview.test.BasicTester

public class BasicTester
extends java.lang.Object

This class does basic testing of the features of the SkyView JAR. It primarily does end-to-end tests of SkyView requests and does a regression of the results against previous values. The results of the previous tests are loaded using a Settings file, comparison.settings.

Using the standard Ant script all testing is done in a temp subdirectory. The comparison.settings and inputtest1.fits file are copied from the source/skyview/test directory into this directory. The actual tests are run using JUnit. JUnit invokes all methods with the Test annotation. If an assertion in any method fails it continues with the next test.

This program does not do many unit tests of individual functions, nor does it test for bugs that may come from particular combinations of features selected by the user. Additional tests can easily be added as appropriate however.

The Ant build script that compiles that Java code will run this script with ant -f build/skyview.xml test. To run only some tests the user can set the environment variables MIN_TEST and MAX_TEST and only the tests that are between these values will be run. Tests are organized in groups with each test numbered. The following ranges define the category associated with each test.

1-99

Checking individual surveys.

101-199

Samplers

201-299

Projections

301-399

Coordinate Systems

401-499

Rotation and Translation

501-599

Pixel scale

601-699

Image sizes in pixels

701-799

Settings control

801-899

Different ways of specifying positions

901-999

Quicklook image formats

1001-1099

Gridding

1101-1199

Contouring

1201-1299

Smoothing

1301-1399

Catalogs

1401-1499

Look up tables

1501-1599

RGB images

1600-1601

Image intensity scaling (log, linear, sqrt)

1701-1799

Plot parameters

Additional tests can be added to any of these, and new categories of tests can be added. Most of the tests <900 test the data in the resulting FITS image. Most of the higher tests test the data in the quicklook image.

Changes to SkyView code will inevitably create changes in the reference values even when there is no error, e.g., just the text in a graphic overlay. Tests will fail when the comparison.settings file has a value for the sum of the appropriate file, and the generated file does not match. To update these, simply delete the corresponding entry in comparison.settings. If a regression test is run and there is no entry in the comparison.settings file, a line is written to the upd.settings file. After the test is run, this file can be concatenated to the comparison.settings (in the source area) for future regression testing.
