Struct TestError 

pub struct TestError(/* private fields */);

An error for test functions that accepts any error supported by a boxed standard error.

Unlike Error, this type deliberately does not implement std::error::Error. This allows it to accept arbitrary errors via From without conflicting with the standard library’s identity conversion. Its Debug output includes the complete error tree or chain and all captured caller locations.
