摘要： Embodiments of the present invention provide systems and methods for multidimensional parts average testing for testing devices and analyzing testing results to detect outliers according to embodiments of the present invention. The testing can include calculating multivariate (e.g., bivariate) statistics using delta measurements of like devices, a ratio of measurements, or principal component analysis that identifies eigenvectors and eigenvalues to define meta parameters, for example. Raw test result data can be converted to residual space and robust regression can be performed to prevent outlier results from influencing regression, thereby reducing overkill advantageously.

摘要： A method of performing a test using automated test equipment (ATE) is disclosed. The method comprises configuring a proxy application programming interface (API) services module, wherein the proxy API services module provides an interface between a test framework and a test software environment, wherein the test framework communicates with the test software environment though the proxy API services module, wherein the test software environment is communicatively coupled with test hardware, and wherein the proxy API services module is configured to isolate the test framework from dependencies associated with the test software environment. The method further comprises communicating commands synchronously between the test framework and the test software environment, wherein the test framework comprises a plurality of components, and wherein the plurality of components is operable to receive commands from the test software environment and further operable to transmit commands to the test software environment through the proxy API services module.
