3 This chapter describes the tests in the `/test` directory, how they are
4 structured and how to extend them. For a quick introduction on how to run
5 the tests, see the [Development setup chapter](Development-Environment.md).
9 There are two kind of tests in this test suite. There are functional tests
10 which test the API interface using a BDD test framework and there are unit
11 tests for specific PHP functions.
13 This test directory is sturctured as follows:
16 -+- bdd Functional API tests
18 | +- steps Step implementations for test descriptions
19 | +- osm2pgsql Tests for data import via osm2pgsql
20 | +- db Tests for internal data processing on import and update
21 | +- api Tests for API endpoints (search, reverse, etc.)
24 +- scenes Geometry test data
25 +- testdb Base data for generating API test database
28 ## PHP Unit Tests (`test/php`)
30 Unit tests can be found in the php/ directory and tests selected php functions.
33 To execute the test suite run
36 UNIT_TEST_DSN='pgsql:dbname=nominatim_unit_tests' phpunit ../
38 It will read phpunit.xml which points to the library, test path, bootstrap
39 strip and set other parameters.
41 It will use (and destroy) a local database 'nominatim_unit_tests'. You can set
42 a different connection string with e.g. UNIT_TEST_DSN='pgsql:dbname=foo_unit_tests'.
44 ## BDD Functional Tests (`test/bdd`)
46 Functional tests are written as BDD instructions. For more information on
47 the philosophy of BDD testing, see the
48 [Behave manual](http://pythonhosted.org/behave/philosophy.html).
50 The following explanation assume that the reader is familiar with the BDD
51 notations of features, scenarios and steps.
53 All possible steps can be found in the `steps` directory and should ideally
58 To run the functional tests, do
63 The tests can be configured with a set of environment variables (`behave -D key=val`):
65 * `BUILDDIR` - build directory of Nominatim installation to test
66 * `TEMPLATE_DB` - name of template database used as a skeleton for
67 the test databases (db tests)
68 * `TEST_DB` - name of test database (db tests)
69 * `API_TEST_DB` - name of the database containing the API test data (api tests)
70 * `DB_HOST` - (optional) hostname of database host
71 * `DB_PORT` - (optional) port of database on host
72 * `DB_USER` - (optional) username of database login
73 * `DB_PASS` - (optional) password for database login
74 * `SERVER_MODULE_PATH` - (optional) path on the Postgres server to Nominatim
75 module shared library file
76 * `TEST_SETTINGS_TEMPLATE` - file to write temporary Nominatim settings to
77 * `REMOVE_TEMPLATE` - if true, the template database will not be reused during
78 the next run. Reusing the base templates speeds up tests
79 considerably but might lead to outdated errors for some
80 changes in the database layout.
81 * `KEEP_TEST_DB` - if true, the test database will not be dropped after a test
82 is finished. Should only be used if one single scenario is
83 run, otherwise the result is undefined.
85 Logging can be defined through command line parameters of behave itself. Check
86 out `behave --help` for details. Also have a look at the 'work-in-progress'
87 feature of behave which comes in handy when writing new tests.
89 ### API Tests (`test/bdd/api`)
91 These tests are meant to test the different API endpoints and their parameters.
92 They require a to import several datasets into a test database.
93 See the [Development Setup chapter](Development-Environment.md#preparing-the-test-database)
94 for instructions on how to set up this database.
96 The official test dataset was derived from the 180924 planet (note: such
97 file no longer exists at https://planet.openstreetmap.org/planet/2018/).
98 Newer planets are likely to work as well but you may see isolated test
99 failures where the data has changed.
101 The official test dataset can always be downloaded from
102 [nominatim.org](https://www.nominatim.org/data/test/nominatim-api-testdata.pbf)
103 To recreate the input data for the test database run:
106 wget https://ftp5.gwdg.de/pub/misc/openstreetmap/planet.openstreetmap.org/pbf/planet-180924.osm.pbf
107 osmconvert planet-180924.osm.pbf -B=test/testdb/testdb.polys -o=testdb.pbf
112 The API tests also support code coverage tests. You need to install
113 [PHP_CodeCoverage](https://github.com/sebastianbergmann/php-code-coverage).
114 On Debian/Ubuntu run:
116 apt-get install php-codecoverage php-xdebug
118 Then run the API tests as follows:
120 behave api -DPHPCOV=<coverage output dir>
122 The output directory must be an absolute path. To generate reports, you can use
123 the [phpcov](https://github.com/sebastianbergmann/phpcov) tool:
125 phpcov merge --html=<report output dir> <coverage output dir>
127 ### DB Creation Tests (`test/bdd/db`)
129 These tests check the import and update of the Nominatim database. They do not
130 test the correctness of osm2pgsql. Each test will write some data into the `place`
131 table (and optionally `the planet_osm_*` tables if required) and then run
132 Nominatim's processing functions on that.
134 These tests need to create their own test databases. By default they will be
135 called `test_template_nominatim` and `test_nominatim`. Names can be changed with
136 the environment variables `TEMPLATE_DB` and `TEST_DB`. The user running the tests
137 needs superuser rights for postgres.
139 ### Import Tests (`test/bdd/osm2pgsql`)
141 These tests check that data is imported correctly into the place table. They
142 use the same template database as the Indexing tests, so the same remarks apply.
