The lnt Tool

The lnt command line utility provides the following commands for client-side use and server-side use. The following is a list of commands and the most importat options, use lnt <toolname> --help for more information on any particular tool.

Client-Side Tools

lnt checkformat [<file>]

Checks the syntax of an LNT test report file. In addition to verifying that LNT can read the raw format (e.g., JSON or property list), this also creates a temporary in-memory database instance and ensures that the test report file can be imported correctly.

If run without arguments, this expects to read the input file from stdin.

lnt convert <input path> [<output path>]
Convert between LNT test report formats. By default, this will convert to the property list format. You can use - for either the input (to read from stdin) or the output (to write to ``stdout).
lnt submit [--commit=1] <server url> <file>+

Submits one or more files to the given server. The <server url> should be the url to the actual submitRun page on the server; the database being submitted to is effectively a part of this URL.

By default, this only submits the report to the server but does not actually commit the data. When testing, you should verify that the server returns an acceptable response before committing runs.

lnt showtests
List available built-in tests. See the Test Producers documentation for more details on this tool.
lnt runtest [<run options>] <test name> ... test arguments ...
Run a built-in test. See the Test Producers documentation for more details on this tool.

Server-Side Tools

The following tools are used to interact with an LNT server:

lnt create <path>

Creates a new LNT server instance. This command has a number of parameters to tweak the generated server, but they can all be modified after the fact in the LNT configuration file.

The default server will have a sqlite3 database named default. You can specify to use PostgreSQL using --db-dir postgresql://user@hostname.

lnt createdb <path>
Creates a new LNT sqlite3 database at the specified path.
lnt import [--commit=1] <instance path> <file>+
Import an LNT data file into a database. You can use --database to select the database to write to. Note that by default this will also generate report emails if enabled in the configuration, you can use --no-email to disable this.
lnt runserver <instance path>
Start the LNT server using a development WSGI server. Additional options can be used to control the server host and port, as well as useful development features such as automatic reloading.
lnt updatedb --database <NAME> --testsuite <NAME> <instance path>

Modify the given database and testsuite.

Currently the only supported commands are --delete-machine and --delete-run.

All commands which take an instance path support passing in either the path to the lnt.cfg file, the path to the instance directory, or the path to a (compressed) tarball. The tarball will be automatically unpacked into a temporary directory and removed on exit. This is useful for testing and for passing database instances back and forth, for example when others only need to be able to view the results.
