12 To get the prerequisites on a a fresh Ubuntu LTS 16.04 run:
14 [sudo] apt-get install python3-dev python3-pip python3-psycopg2 python3-tidylib phpunit
15 pip3 install --user behave nose
21 There are two kind of tests in this test suite. There are functional tests
22 which test the API interface using a BDD test framework and there are unit
23 tests for specific PHP functions.
25 This test directory is sturctured as follows:
27 -+- bdd Functional API tests
29 | +- steps Step implementations for test descriptions
30 | +- osm2pgsql Tests for data import via osm2pgsql
31 | +- db Tests for internal data processing on import and update
32 | +- api Tests for API endpoints (search, reverse, etc.)
35 +- scenes Geometry test data
36 +- testdb Base data for generating API test database
42 Unit tests can be found in the php/ directory and tests selected php functions.
45 To execute the test suite run
50 It will read phpunit.xml which points to the library, test path, bootstrap
51 strip and set other parameters.
57 Functional tests are written as BDD instructions. For more information on
58 the philosophy of BDD testing, see http://pythonhosted.org/behave/philosophy.html
63 To run the functional tests, do
68 The tests can be configured with a set of environment variables:
70 * `BUILD_DIR` - build directory of Nominatim installation to test
71 * `TEMPLATE_DB` - name of template database used as a skeleton for
72 the test databases (db tests)
73 * `TEST_DB` - name of test database (db tests)
74 * `ABI_TEST_DB` - name of the database containing the API test data (api tests)
75 * `TEST_SETTINGS_TEMPLATE` - file to write temporary Nominatim settings to
76 * `REMOVE_TEMPLATE` - if true, the template database will not be reused during
77 the next run. Reusing the base templates speeds up tests
78 considerably but might lead to outdated errors for some
79 changes in the database layout.
80 * `KEEP_TEST_DB` - if true, the test database will not be dropped after a test
81 is finished. Should only be used if one single scenario is
82 run, otherwise the result is undefined.
84 Logging can be defined through command line parameters of behave itself. Check
85 out `behave --help` for details. Also keep an eye out for the 'work-in-progress'
86 feature of behave which comes in handy when writing new tests.
91 The following explanation assume that the reader is familiar with the BDD
92 notations of features, scenarios and steps.
94 All possible steps can be found in the `steps` directory and should ideally
97 ### API Tests (`test/bdd/api`)
99 These tests are meant to test the different API endpoints and their parameters.
100 They require a preimported test database, which consists of the import of a
101 planet extract. The polygons defining the extract can be found in the test/testdb
102 directory. There is also a reduced set of wikipedia data for this extract,
103 which you need to import as well.
105 The official test dataset is derived from the 160725 planet. Newer
106 planets are likely to work as well but you may see isolated test
107 failures where the data has changed. To recreate the input data
108 for the test database run:
110 wget http://free.nchc.org.tw/osm.planet/pbf/planet-160725.osm.pbf
111 osmconvert planet-160725.osm.pbf -B=test/testdb/testdb.polys -o=testdb.pbf
113 Before importing make sure to add the following to your local settings:
115 @define('CONST_Database_DSN', 'pgsql://@/test_api_nominatim');
116 @define('CONST_Wikipedia_Data_Path', CONST_BasePath.'/test/testdb');
118 ### Indexing Tests (`test/bdd/db`)
120 These tests check the import and update of the Nominatim database. They do not
121 test the correctness of osm2pgsql. Each test will write some data into the `place`
122 table (and optionally `the planet_osm_*` tables if required) and then run
123 Nominatim's processing functions on that.
125 These tests need to create their own test databases. By default they will be
126 called `test_template_nominatim` and `test_nominatim`. Names can be changed with
127 the environment variables `TEMPLATE_DB` and `TEST_DB`. The user running the tests
128 needs superuser rights for postgres.
130 ### Import Tests (`test/bdd/osm2pgsql`)
132 These tests check that data is imported correctly into the place table. They
133 use the same template database as the Indexing tests, so the same remarks apply.
