67 68 69 70 71 72 73 | An ALWAYS(X) or NEVER(X) macro, or something similar, should be used in those cases because ALWAYS(X) or NEVER(X) will be followed by code to actually deal with the problem when the programmers reasoning turns out to be wrong. Since the code that follows ALWAYS(X) or NEVER(X) is untested, it should be something very simple, like a "return" statement, that is easily verified by inspection. | > > > | < < | < | | > | 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 | An ALWAYS(X) or NEVER(X) macro, or something similar, should be used in those cases because ALWAYS(X) or NEVER(X) will be followed by code to actually deal with the problem when the programmers reasoning turns out to be wrong. Since the code that follows ALWAYS(X) or NEVER(X) is untested, it should be something very simple, like a "return" statement, that is easily verified by inspection. <p> Because assert() can be and is commonly misused, some programming language theorists and designers look with disfavor on the whole idea of assert(). For example, the [https://golang.org|Go programming language] omits assert(). The Go developers [https://golang.org/doc/faq#assertions|recognize this is contentious]. The SQLite developers agree with those that think the decision to omit assert() from Go is a mistake. It is true that assert() can be misused. Antibiotics can be misused too, but that does not mean we should ban all antibiotics. <h2>Different Behaviors According To Build Type</h2> <p>Three separate builds are used to validate the SQLite software. <ol> <li> A functionality testing build is used to validate the source code. <li> A coverage testing build is used to validate the test suite, to confirm |
