1 This directory contains functional and unit tests for the Nominatim API.
6 * Python 3 (https://www.python.org/)
7 * behave test framework >= 1.2.5 (https://github.com/behave/behave)
8 * nose (https://nose.readthedocs.org)
9 * pytidylib (http://countergram.com/open-source/pytidylib)
10 * psycopg2 (http://initd.org/psycopg/)
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
49 UNIT_TEST_DSN='pgsql:dbname=nominatim_unit_tests' phpunit ../
51 It will read phpunit.xml which points to the library, test path, bootstrap
52 strip and set other parameters.
54 It will use (and destroy) a local database 'nominatim_unit_tests'. You can set
55 a different connection string with e.g. UNIT_TEST_DSN='pgsql:dbname=foo_unit_tests'.
60 Functional tests are written as BDD instructions. For more information on
61 the philosophy of BDD testing, see http://pythonhosted.org/behave/philosophy.html
66 To run the functional tests, do
71 The tests can be configured with a set of environment variables (`behave -D key=val`):
73 * `BUILDDIR` - build directory of Nominatim installation to test
74 * `TEMPLATE_DB` - name of template database used as a skeleton for
75 the test databases (db tests)
76 * `TEST_DB` - name of test database (db tests)
77 * `API_TEST_DB` - name of the database containing the API test data (api tests)
78 * `DB_HOST` - (optional) hostname of database host
79 * `DB_PORT` - (optional) port of database on host
80 * `DB_USER` - (optional) username of database login
81 * `DB_PASS` - (optional) password for database login
82 * `SERVER_MODULE_PATH` - (optional) path on the Postgres server to Nominatim
83 module shared library file
84 * `TEST_SETTINGS_TEMPLATE` - file to write temporary Nominatim settings to
85 * `REMOVE_TEMPLATE` - if true, the template database will not be reused during
86 the next run. Reusing the base templates speeds up tests
87 considerably but might lead to outdated errors for some
88 changes in the database layout.
89 * `KEEP_TEST_DB` - if true, the test database will not be dropped after a test
90 is finished. Should only be used if one single scenario is
91 run, otherwise the result is undefined.
93 Logging can be defined through command line parameters of behave itself. Check
94 out `behave --help` for details. Also keep an eye out for the 'work-in-progress'
95 feature of behave which comes in handy when writing new tests.
100 The following explanation assume that the reader is familiar with the BDD
101 notations of features, scenarios and steps.
103 All possible steps can be found in the `steps` directory and should ideally
106 ### API Tests (`test/bdd/api`)
108 These tests are meant to test the different API endpoints and their parameters.
109 They require a preimported test database, which consists of the import of a
110 planet extract. A precompiled PBF with the necessary data can be downloaded from
111 https://www.nominatim.org/data/test/nominatim-api-testdata.pbf
113 You need at least 2GB RAM and 10GB discspace.
115 The polygons defining the extract can be found in the test/testdb
116 directory. There is also a reduced set of wikipedia data for this extract,
117 which you need to import as well. For Tiger tests the data of South Dakota
118 is required. Get the Tiger files `46*`.
121 wget https://nominatim.org/data/tiger2018-nominatim-preprocessed.tar.gz
122 tar xvf tiger2018-nominatim-preprocessed.tar.gz --wildcards --no-anchored '46*'
123 rm tiger2018-nominatim-preprocessed.tar.gz
125 The official test dataset is derived from the 180924 planet. Newer
126 planets are likely to work as well but you may see isolated test
127 failures where the data has changed. To recreate the input data
128 for the test database run:
130 wget https://ftp5.gwdg.de/pub/misc/openstreetmap/planet.openstreetmap.org/pbf/planet-180924.osm.pbf
131 osmconvert planet-180924.osm.pbf -B=test/testdb/testdb.polys -o=testdb.pbf
133 Before importing make sure to add the following to your local settings:
135 @define('CONST_Database_DSN', 'pgsql://@/test_api_nominatim');
136 @define('CONST_Wikipedia_Data_Path', CONST_BasePath.'/test/testdb');
140 The API tests also support code coverage tests. You need to install
141 [PHP_CodeCoverage](https://github.com/sebastianbergmann/php-code-coverage).
142 On Debian/Ubuntu run:
144 apt-get install php-codecoverage php-xdebug
146 The run the API tests as follows:
148 behave api -DPHPCOV=<coverage output dir>
150 The output directory must be an absolute path. To generate reports, you can use
151 the [phpcov](https://github.com/sebastianbergmann/phpcov) tool:
153 phpcov merge --html=<report output dir> <coverage output dir>
155 ### Indexing Tests (`test/bdd/db`)
157 These tests check the import and update of the Nominatim database. They do not
158 test the correctness of osm2pgsql. Each test will write some data into the `place`
159 table (and optionally `the planet_osm_*` tables if required) and then run
160 Nominatim's processing functions on that.
162 These tests need to create their own test databases. By default they will be
163 called `test_template_nominatim` and `test_nominatim`. Names can be changed with
164 the environment variables `TEMPLATE_DB` and `TEST_DB`. The user running the tests
165 needs superuser rights for postgres.
167 ### Import Tests (`test/bdd/osm2pgsql`)
169 These tests check that data is imported correctly into the place table. They
170 use the same template database as the Indexing tests, so the same remarks apply.
