Is test pane meaningful?

I see it added in packages/plugin-ext/src/main/browser/view/plugin-view-registry.ts:

    this.doRegisterViewContainer('test', 'left', {
        label: 'Test',
        iconClass: 'theia-plugin-test-tab-icon',
        closeable: true
    });

Is it used?

@amiramw from my understanding, the ‘test view’ is used by plugins who contribute views to it (ex: python). You may see the issue: https://github.com/eclipse-theia/theia/issues/7081
