Description
Currently, qmltc does not try to find and load qmllint plugins when compiling. For example, lets say a qml file has an invalid quick type, and qmllint warns about it when it loads the quick plugin: if qmltc is run on the same file, it will internally run the linter without the plugins (and will not get the warning that one of the quick types is invalid) and will then attempt to compile an invalid QML file, leading potentially to generating incorrect code.
An example of this is in https://codereview.qt-project.org/c/qt/qtdeclarative/+/514494 in the tst_qmltc_qprocess:constructFromString test that is QEXPECT_FAIL.
Currently, qmltc is not aware of value type constructors, for example it does not know how to construct the quick vector type:Main.qml
currently (current 6.8 snapshot) gives:
