|kyua db-migrate||[--results-file file]|
The kyua db-migrate command migrates the schema of an existing database to the latest version implemented in kyua(1).
This operation is not reversible. However, a backup of the database is created in the same directory where the database lives.
The following subcommand options are recognized:
- --results-file path, -s path
Specifies the results file to operate on. Defaults to ‘LATEST’, which causes kyua db-migrate to automatically load the latest results file from the current test suite.
The following values are accepted:
Requests the load of the latest results file available for the test suite rooted at the current directory.
Requests the load of the latest results file available for the test suite rooted at the given directory.
- Test suite name
Requests the load of the latest results file available for the given test suite.
- Results identifier
Requests the load of a specific results file.
- Explicit file name (aka everything else)
Load the specified results file.
See Results files for more details.
Results files contain, as their name implies, the results of the execution of a test suite. Each test suite executed by kyua-test(1) generates a new results file, and such results files can be loaded later on by inspection commands such as kyua-report(1) to analyze their contents.
Results files support identifier-based lookups and also path name lookups. The differences between the two are described below.
The default naming scheme for the results files provides simple support for identifier-based lookups and historical recording of test suite runs. Each results file is given an identifier derived from the test suite that generated it and the time the test suite was run. Kyua can later look up results files by these fileds.
The identifier follows this pattern:
where ‘test_suite’ is the path to the root of the test suite that was run with all slashes replaced by underscores and ‘YYYYMMDD-HHMMSS-uuuuuu’ is a timestamp with microsecond resolution.
When using the default naming scheme, results files are stored in the
~/.kyua/store/ subdirectory and each file holds a name of the form:
Results files are simple SQLite databases with the schema described in the
/usr/share/kyua/store/schema_v?.sql files. For details on the schema, please refer to the heavily commented SQL file.
The kyua db-migrate command returns 0 on success or 1 if the migration fails.
Additional exit codes may be returned as described in kyua(1).
