No, It wasn't really. But science tests itself by taking into account multiple theories which can agree with each other. Like in biology. Biology is made up of a multitude of theories which when taken together cross confirm and support each other which lend credence to each individual theory.
And while it is true that newtonian physics, relativity and quantum physics don't really mesh with each other, that doesn't make them any less valid individually. Science tests itself by correcting it's mistakes like throwing out theories we know don't work (like phlogiston theory and aether theory are just a couple examples). Peer review and disclosure are another couple of ways science tests itself. If the tests are done over and over and continue to produce different results, the results of no single session may be used as evidence. If the peers find the scientists to be biased then the research can't be used as evidence. Science is constantly in a stated of making sure the findings are valid.
No, Science doesn't test it self because science is a systematic knowledge of the physical or material world gained through observation and experimentation. Scientists do tests and experiments and provide peer reviewed disclosures. Science doesn't test Science.
