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 php-cgi
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:
28 -+- bdd Functional API tests
30 | +- steps Step implementations for test descriptions
31 | +- osm2pgsql Tests for data import via osm2pgsql
32 | +- db Tests for internal data processing on import and update
33 | +- api Tests for API endpoints (search, reverse, etc.)
36 +- scenes Geometry test data
37 +- testdb Base data for generating API test database
43 Unit tests can be found in the php/ directory and tests selected php functions.
46 To execute the test suite run
51 It will read phpunit.xml which points to the library, test path, bootstrap
52 strip and set other parameters.
58 Functional tests are written as BDD instructions. For more information on
59 the philosophy of BDD testing, see http://pythonhosted.org/behave/philosophy.html
64 To run the functional tests, do
69 The tests can be configured with a set of environment variables (`behave -D key=val`):
71 * `BUILDDIR` - build directory of Nominatim installation to test
72 * `TEMPLATE_DB` - name of template database used as a skeleton for
73 the test databases (db tests)
74 * `TEST_DB` - name of test database (db tests)
75 * `API_TEST_DB` - name of the database containing the API test data (api tests)
76 * `DB_HOST` - (optional) hostname of database host
77 * `DB_PORT` - (optional) port of database on host
78 * `DB_USER` - (optional) username of database login
79 * `DB_PASS` - (optional) password for database login
80 * `SERVER_MODULE_PATH` - (optional) path on the Postgres server to Nominatim
81 module shared library file
82 * `TEST_SETTINGS_TEMPLATE` - file to write temporary Nominatim settings to
83 * `REMOVE_TEMPLATE` - if true, the template database will not be reused during
84 the next run. Reusing the base templates speeds up tests
85 considerably but might lead to outdated errors for some
86 changes in the database layout.
87 * `KEEP_TEST_DB` - if true, the test database will not be dropped after a test
88 is finished. Should only be used if one single scenario is
89 run, otherwise the result is undefined.
91 Logging can be defined through command line parameters of behave itself. Check
92 out `behave --help` for details. Also keep an eye out for the 'work-in-progress'
93 feature of behave which comes in handy when writing new tests.
98 The following explanation assume that the reader is familiar with the BDD
99 notations of features, scenarios and steps.
101 All possible steps can be found in the `steps` directory and should ideally
104 ### API Tests (`test/bdd/api`)
106 These tests are meant to test the different API endpoints and their parameters.
107 They require a preimported test database, which consists of the import of a
108 planet extract. A precompiled PBF with the necessary data can be downloaded from
109 https://www.nominatim.org/data/test/nominatim-api-testdata.pbf
111 You need at least 2GB RAM and 10GB discspace.
113 The polygons defining the extract can be found in the test/testdb
114 directory. There is also a reduced set of wikipedia data for this extract,
115 which you need to import as well. For Tiger tests the data of South Dakota
116 is required. Get the Tiger files `46*`.
119 wget https://nominatim.org/data/tiger2018-nominatim-preprocessed.tar.gz
120 tar xvf tiger2018-nominatim-preprocessed.tar.gz --wildcards --no-anchored '46*'
121 rm tiger2018-nominatim-preprocessed.tar.gz
123 The official test dataset is derived from the 180924 planet. Newer
124 planets are likely to work as well but you may see isolated test
125 failures where the data has changed. To recreate the input data
126 for the test database run:
128 wget https://ftp5.gwdg.de/pub/misc/openstreetmap/planet.openstreetmap.org/pbf/planet-180924.osm.pbf
129 osmconvert planet-180924.osm.pbf -B=test/testdb/testdb.polys -o=testdb.pbf
131 Before importing make sure to add the following to your local settings:
133 @define('CONST_Database_DSN', 'pgsql://@/test_api_nominatim');
134 @define('CONST_Wikipedia_Data_Path', CONST_BasePath.'/test/testdb');
138 The API tests also support code coverage tests. You need to install
139 [PHP_CodeCoverage](https://github.com/sebastianbergmann/php-code-coverage).
140 On Debian/Ubuntu run:
142 apt-get install php-codecoverage php-xdebug
144 The run the API tests as follows:
146 behave api -DPHPCOV=<coverage output dir>
148 The output directory must be an absolute path. To generate reports, you can use
149 the [phpcov](https://github.com/sebastianbergmann/phpcov) tool:
151 phpcov merge --html=<report output dir> <coverage output dir>
153 ### Indexing Tests (`test/bdd/db`)
155 These tests check the import and update of the Nominatim database. They do not
156 test the correctness of osm2pgsql. Each test will write some data into the `place`
157 table (and optionally `the planet_osm_*` tables if required) and then run
158 Nominatim's processing functions on that.
160 These tests need to create their own test databases. By default they will be
161 called `test_template_nominatim` and `test_nominatim`. Names can be changed with
162 the environment variables `TEMPLATE_DB` and `TEST_DB`. The user running the tests
163 needs superuser rights for postgres.
165 ### Import Tests (`test/bdd/osm2pgsql`)
167 These tests check that data is imported correctly into the place table. They
168 use the same template database as the Indexing tests, so the same remarks apply.
