Deductive Software Verification – The KeY Book
From Theory to Practice


Available at Springer

bookcover

The new book covers deductive software verification as realised by the KeY approach. It constitutes the ultimate source for the KeY tool since version 2.x.

It also features a general (not KeY specific) chapter on the Java Modeling Language which provides a thorough introduction into the specification language.

The book differs significantly from its first edition. Almost all chapters are either new or largely rewritten. It encompasses the experiences learned between the years 2006-2016.

The KeY book is available at Springer Online (LNCS 10001) and at Springer Link.

Preprints are in many cases available on the author’s websites and linked from the table of contents below.

Errata (found after publishing)

page 30, Figure 2.2
The correct version of the rule eqRight should read:

page 202, Example 7.6
The sentence says
“To specify that a method returns the index of an integer array arr holding the maximum entry, we can write the following postcondition,”
but should say
“… the maximum element of an integer array arr.”

page 269, Definition 8.3
The defined tuple (pre, var, dep) must read (pre, term, dep) to be consistent with the text. var was short for variant, and term stands for termination witness.

page 321, Section 9.3.1 right before Listing 9.8
The last occurrence of accessible before Listing 9.8 must read assignable.
