The output XML contains nested `testsuites` → `testsuite` → `testcase` tags. You can customize the reporter's behaviour with the following options:

| Option | Description | Default |

|---|---|---|

| `suiteName` | `name` attribute of `<testsuites>` | `"vitest tests"` |

| `suiteNameTemplate` | Template for the `name` attribute of `<testsuite>`. Accepts a string with placeholders or a function. | Relative file path |

| `classnameTemplate` | Template for the `classname` attribute of `<testcase>`. Accepts a string with placeholders or a function. | Relative file path |

| `titleTemplate` | Template for the `name` attribute of `<testcase>`. Accepts a string with placeholders or a function. | Full test title with ancestor hierarchy |

| `ancestorSeparator` | Separator used when joining ancestor describe block names in the `{classname}` placeholder and in the default test title. | `" > "` |

| `addFileAttribute` | Add a `file` attribute to each `<testcase>`. | `false` |

| `includeConsoleOutput` | Include `<system-out>` / `<system-err>` console output. | `true` |

| `stackTrace` | Include stack traces in `<failure>` elements. | `true` |

The following placeholders are available for `suiteNameTemplate`:

- `{title}` – name of the first top-level `describe` block; falls back to the file basename when there is no top-level `describe`

- `{filename}` – relative file path from the root (e.g. `src/foo.test.ts`)

- `{filepath}` – absolute file path

- `{basename}` – file name without directory (e.g. `foo.test.ts`)

- `{displayName}` – Vitest project name

The following placeholders are available for `classnameTemplate` and `titleTemplate`:

- `{classname}` – ancestor `describe` block names joined by `ancestorSeparator` (e.g. `outer > inner`)

- `{title}` – leaf test title (the string passed to `it`/`test`)

- `{suitename}` – top-level `describe` block name, empty string when the test has no enclosing `describe`

- `{filename}` – relative file path from the root

- `{filepath}` – absolute file path

- `{basename}` – file name without directory

- `{displayName}` – Vitest project name

::: tip

`{filename}` follows Vitest's convention and resolves to the **relative path** from the project root (e.g. `src/foo.test.ts`). This differs from jest-junit where `{filename}` is the bare file name. Use `{basename}` to get only the file name.

:::

export default defineConfig({

test: {

reporters: [

['junit', {

suiteName: 'My Test Suite',

// Use the first top-level describe block name as the testsuite name

suiteNameTemplate: '{title}',

// classname = ancestor describe chain

classnameTemplate: '{classname}',

// name = leaf test title only (jest-junit-compatible)

titleTemplate: '{title}',

ancestorSeparator: ' > ',

}]

]

},

})

Function-based templates receive all available variables and can return any string:

['junit', {

classnameTemplate: ({ classname, filename }) =>

classname ? `${filename}::${classname}` : filename,

titleTemplate: ({ suitename, title }) =>

suitename ? `[${suitename}] ${title}` : title,

}]
