Function TestCreateDatabaseGroup

backend/tests/grouping_change_test.go:21–183

TestCreateDatabaseGroup tests creating database and verify the grouping result. For each test case: 1. The test provides a number of sqlite instances equal to the number of prepareInstances and creates the specified matchDatabase and unmatchedDatabase in the corresponding instances. 2. The database

(t *testing.T)

// 2. The database group is then created with the specified expr.
// 3. The results obtained are compared with the results given in prepareInstance and they should be consistent.
