The developers of X11 made X11 nonfree for a while; they were able to do this because others had contributed their code under the same noncopyleft license. Tests are based on the requirements and functionality. It is a Black-box type testing geared to the functional requirements of an application. For instance, if the disk in which the computer program is being installed was full, the installer may ask the user to specify another target path or clear enough space in the disk. If a compiler can prove that a program is well-typed, then it does not need to emit dynamic safety checks, allowing the resulting compiled binary to run faster and to be smaller. Expected is the behavior predicted by the specification, or another source, of the component or system under specified conditions. As computing environments grew more complex and fixed replaced , the need for tangible installation presented itself.
