# [Name](#Name)

gtester - test running utility

# [SYNOPSIS](#SYNOPSIS)

```
gtester [OPTION…] test-program
```

# [DESCRIPTION](#DESCRIPTION)

**gtester** is a utility to run unit tests that have been written using the GLib test framework.

Since GLib 2.62, **gtester-report** is deprecated. Use TAP for reporting test results instead, and feed it to the test harness provided by your build system.

When called with the **-o** option, **gtester** writes an XML report of the test results, which can be converted into HTML using the **gtester-report** utility.
