Dynamic program analysis is the analysis of computer software that is performed by executing programs on a real or virtual processor. For dynamic program analysis to be effective, the target program must be executed with sufficient test inputs to produce interesting behavior. Use of software testing techniques such as code coverage helps ensure that an adequate slice of the program's set of possible behaviors has been observed. Also, care must be taken to minimize the effect that instrumentation has on the execution (including temporal properties) of the target program. Inadequate testing can lead to catastrophic failures similar to the maiden flight of the Ariane 5 rocket launcher where dynamic execution errors (run time error) resulted in the destruction of the vehicle.

Famous quotes containing the words dynamic, program and/or analysis:
“The nearer a conception comes towards finality, the nearer does the dynamic relation, out of which this concept has arisen, draw to a close. To know is to lose.”
—D.H. (David Herbert)
“Mead had studied for the ministry, but had lost his faith and took great delight in blasphemy. Capt. Charles H. Frady, pioneer missionary, held a meeting here and brought Mead back into the fold. He then became so devout that, one Sunday, when he happened upon a swimming party, he shot at the people in the river, and threatened to kill anyone he again caught desecrating the Sabbath.”
—For the State of Nebraska, U.S. public relief program (1935-1943)
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
