The document provides a history of software testing from the 1950s to 2010. It outlines some of the major developments in testing techniques over the decades, including decision tables in 1957, equivalence partitioning and boundary value analysis in the late 1960s, cause-effect graphs in 1970, orthogonal arrays and combinatorial testing techniques from the 1980s onward, and model-based techniques like classification trees in the 1990s and covering arrays in the 2000s. The timeline shows when key techniques and methods were developed.
