autowisp.tests.test_diagnostic_expressions module

Class Inheritance Diagram

Tests for the diagnostic expression library stored in a project.

The library is read and written through autowisp.diagnostics.expression_library, against a throwaway project database. What an expression means is tested where those rules live, in the expression layer’s own tests; here it is only what gets stored, and that references survive a rename.

The management form is tested here too, for the one check it makes itself rather than delegating: that a name is a slug and is not already taken.

class autowisp.tests.test_diagnostic_expressions.ExpressionLibraryTestCase(methodName='runTest')

Bases: TestCase

Base creating one throwaway project, emptied before every test.

static library()

The stored library, {name: expression}.

static make(name, expression='astrom_residual[0] / diagonal_fov[0]', **kw)

Store one expression, returning what the store reported.

setUp()

Hook method for setting up the test fixture before exercising it.

classmethod setUpClass()

Hook method for setting up class fixture before running tests in the class.

classmethod tearDownClass()

Hook method for deconstructing the class fixture after running all tests in the class.

class autowisp.tests.test_diagnostic_expressions.TestDeleteAndWrite(methodName='runTest')

Bases: ExpressionLibraryTestCase

Deleting several, and writing an import’s worth at once.

test_delete_only_the_named()

Other expressions, and names not stored, are left alone.

test_write_counts_added_and_replaced()

New names are added, existing ones overwritten, and counted.

class autowisp.tests.test_diagnostic_expressions.TestExpressionForm(methodName='runTest')

Bases: TestCase

The name checks the management form makes itself.

form(name, replacing=None)

Bind the form to one proposed expression.

library = {'rel_bg': 'bg_center[0] - nanmedian(bg_center[0])'}

test_a_slug_name_is_accepted()

The names the documentation suggests actually validate.

test_a_taken_name_is_refused()

Adding under a stored name would replace it without asking.

test_editing_keeps_its_own_name()

The expression being edited does not clash with itself.

test_name_must_survive_a_url()

Rejected unless it is a slug.

Expressions are selected through image/<slug:x>/vs/<slug:y>, so a name outside the slug charset could be stored but never plotted.

test_renaming_onto_another_is_refused()

A rename may not take a name some other expression has.

class autowisp.tests.test_diagnostic_expressions.TestLibraryAccess(methodName='runTest')

Bases: ExpressionLibraryTestCase

What reading hands to the expression layer and to an export.

test_empty_library_is_a_dictionary()

Not None: the layers below iterate it without checking.

test_entries_for_export()

Every stored field, by name, skipping names not stored.

test_names_map_to_their_text()

The shape the expression layer expects, and nothing more.

class autowisp.tests.test_diagnostic_expressions.TestNameSpace(methodName='runTest')

Bases: ExpressionLibraryTestCase

Names have to behave like the diagnostic names they sit beside.

test_name_is_unique()

Two expressions cannot share a name.

The name is what a selector and a URL carry, and what other expressions and exclusion rules reference, so a duplicate would be ambiguous everywhere at once. The form refuses one first; this is the database guaranteeing it regardless.

class autowisp.tests.test_diagnostic_expressions.TestStoreExpression(methodName='runTest')

Bases: ExpressionLibraryTestCase

Adding, replacing and renaming one expression.

test_rename_carries_the_dependents()

What referenced the old name references the new one.

Leaving them naming something that no longer exists would break them, and refusing the rename would not help: a dependent cannot be pointed at the new name before it exists.

test_replacing_a_name_not_stored_adds()

A stale edit link adds the expression rather than losing it.

test_replacing_keeps_the_name()

An edit that keeps the name changes the text in place.

class autowisp.tests.test_diagnostic_expressions.TestStoredFields(methodName='runTest')

Bases: ExpressionLibraryTestCase

What the library keeps, and what it deliberately does not check.

test_description_is_optional()

Most expressions are self-explanatory from their text.

test_unknown_names_are_not_rejected_here()

The library stores text; resolving names is not its job.

An expression may legitimately reference diagnostics the project has never recorded – it is then simply not offered – so refusing it here would be wrong.
