50 | ;;;; CORE FUNCTIONS |
51 | ;;;; | |
52 | ;;;; The function (run-test name expected-result thunk) is the heart of the | |
53 | ;;;; testing environment. The first parameter NAME is a unique name for the | |
54 | ;;;; test to be executed (for an explanation of this parameter see below under | |
55 | ;;;; TEST NAMES). The second parameter EXPECTED-RESULT is a boolean value | |
56 | ;;;; that indicates whether the corresponding test is expected to pass. If | |
57 | ;;;; EXPECTED-RESULT is #t the test is expected to pass, if EXPECTED-RESULT is | |
58 | ;;;; #f the test is expected to fail. Finally, THUNK is the function that | |
59 | ;;;; actually performs the test. For example: | |
60 | ;;;; | |
61 | ;;;; (run-test "integer addition" #t (lambda () (= 2 (+ 1 1)))) | |
62 | ;;;; | |
63 | ;;;; To report success, THUNK should either return #t or throw 'pass. To | |
64 | ;;;; report failure, THUNK should either return #f or throw 'fail. If THUNK | |
65 | ;;;; returns a non boolean value or throws 'unresolved, this indicates that | |
66 | ;;;; the test did not perform as expected. For example the property that was | |
67 | ;;;; to be tested could not be tested because something else went wrong. | |
68 | ;;;; THUNK may also throw 'untested to indicate that the test was deliberately | |
69 | ;;;; not performed, for example because the test case is not complete yet. | |
70 | ;;;; Finally, if THUNK throws 'unsupported, this indicates that this test | |
71 | ;;;; requires some feature that is not available in the configured testing | |
72 | ;;;; environment. All other exceptions thrown by THUNK are considered as | |
73 | ;;;; errors. | |

76 | ;;;; Convenience macros for tests expected to pass or fail | |
77 | ;;;; | |
57e7f270 DH |
78 | ;;;; * (pass-if name body) is a short form for |
79 | ;;;; (run-test name #t (lambda () body)) | |
80 | ;;;; * (expect-fail name body) is a short form for | |
81 | ;;;; (run-test name #f (lambda () body)) | |
82 | ;;;; | |
83 | ;;;; For example: | |
84 | ;;;; | |
85 | ;;;; (pass-if "integer addition" (= 2 (+ 1 1))) | |
6b4113af DH |
86 | ;;;; |
87 | ;;;; | |
88 | ;;;; Convenience macros to test for exceptions | |
89 | ;;;; | |
90 | ;;;; The following macros take exception parameters which are pairs | |
91 | ;;;; (type . message), where type is a symbol that denotes an exception type | |
92 | ;;;; like 'wrong-type-arg or 'out-of-range, and message is a string holding a | |
93 | ;;;; regular expression that describes the error message for the exception | |
94 | ;;;; like "Argument .* out of range". | |
95 | ;;;; | |
96 | ;;;; * (pass-if-exception name exception body) will pass if the execution of | |
97 | ;;;; body causes the given exception to be thrown. If no exception is | |
98 | ;;;; thrown, the test fails. If some other exception is thrown, is is an | |
99 | ;;;; error. | |
100 | ;;;; * (expect-fail-exception name exception body) will pass unexpectedly if | |
101 | ;;;; the execution of body causes the given exception to be thrown. If no | |
102 | ;;;; exception is thrown, the test fails expectedly. If some other | |
103 | ;;;; exception is thrown, it is an error. | |

106 | ;;;; TEST NAMES |
107 | ;;;; | |
108 | ;;;; Every test in the test suite has a unique name, to help | |
109 | ;;;; developers find tests that are failing (or unexpectedly passing), | |
110 | ;;;; and to help gather statistics. | |
111 | ;;;; | |
112 | ;;;; A test name is a list of printable objects. For example: | |
113 | ;;;; ("ports.scm" "file" "read and write back list of strings") | |
114 | ;;;; ("ports.scm" "pipe" "read") | |
115 | ;;;; | |
116 | ;;;; Test names may contain arbitrary objects, but they always have | |
117 | ;;;; the following properties: | |
118 | ;;;; - Test names can be compared with EQUAL?. | |
119 | ;;;; - Test names can be reliably stored and retrieved with the standard WRITE | |
120 | ;;;; and READ procedures; doing so preserves their identity. | |
121 | ;;;; | |
000ee07f JB |
122 | ;;;; For example: |
123 | ;;;; | |
57e7f270 | 124 | ;;;; (pass-if "simple addition" (= 4 (+ 2 2))) |
000ee07f JB |
125 | ;;;; |
126 | ;;;; In that case, the test name is the list ("simple addition"). | |
127 | ;;;; | |
128 | ;;;; The WITH-TEST-PREFIX syntax and WITH-TEST-PREFIX* procedure establish | |
129 | ;;;; a prefix for the names of all tests whose results are reported | |
130 | ;;;; within their dynamic scope. For example: | |
131 | ;;;; | |
132 | ;;;; (begin | |
133 | ;;;; (with-test-prefix "basic arithmetic" | |
134 | ;;;; (pass-if "addition" (= (+ 2 2) 4)) | |
05c4ba00 | 135 | ;;;; (pass-if "subtraction" (= (- 4 2) 2))) |
000ee07f JB |
136 | ;;;; (pass-if "multiplication" (= (* 2 2) 4))) |
137 | ;;;; | |
138 | ;;;; In that example, the three test names are: | |
139 | ;;;; ("basic arithmetic" "addition"), | |
05c4ba00 | 140 | ;;;; ("basic arithmetic" "subtraction"), and |
000ee07f JB |
141 | ;;;; ("multiplication"). |
142 | ;;;; | |
143 | ;;;; WITH-TEST-PREFIX can be nested. Each WITH-TEST-PREFIX postpends | |
144 | ;;;; a new element to the current prefix: | |
145 | ;;;; | |
146 | ;;;; (with-test-prefix "arithmetic" | |
147 | ;;;; (with-test-prefix "addition" | |
148 | ;;;; (pass-if "integer" (= (+ 2 2) 4)) | |
149 | ;;;; (pass-if "complex" (= (+ 2+3i 4+5i) 6+8i))) | |
150 | ;;;; (with-test-prefix "subtraction" | |
151 | ;;;; (pass-if "integer" (= (- 2 2) 0)) | |
152 | ;;;; (pass-if "complex" (= (- 2+3i 1+2i) 1+1i)))) | |
153 | ;;;; | |
154 | ;;;; The four test names here are: | |
155 | ;;;; ("arithmetic" "addition" "integer") | |
156 | ;;;; ("arithmetic" "addition" "complex") | |
157 | ;;;; ("arithmetic" "subtraction" "integer") | |
158 | ;;;; ("arithmetic" "subtraction" "complex") | |
159 | ;;;; | |
160 | ;;;; To print a name for a human reader, we DISPLAY its elements, | |
161 | ;;;; separated by ": ". So, the last set of test names would be | |
162 | ;;;; reported as: | |
163 | ;;;; | |
164 | ;;;; arithmetic: addition: integer | |
165 | ;;;; arithmetic: addition: complex | |
166 | ;;;; arithmetic: subtraction: integer | |
167 | ;;;; arithmetic: subtraction: complex | |
168 | ;;;; | |
169 | ;;;; The Guile benchmarks use with-test-prefix to include the name of | |
170 | ;;;; the source file containing the test in the test name, to help | |
171 | ;;;; developers to find failing tests, and to provide each file with its | |
172 | ;;;; own namespace. | |

175 | ;;;; REPORTERS | |
57e7f270 | 176 | ;;;; |
000ee07f JB |
177 | ;;;; A reporter is a function which we apply to each test outcome. |
178 | ;;;; Reporters can log results, print interesting results to the | |
179 | ;;;; standard output, collect statistics, etc. | |
180 | ;;;; | |
57e7f270 DH |
181 | ;;;; A reporter function takes two mandatory arguments, RESULT and TEST, and |
182 | ;;;; possibly additional arguments depending on RESULT; its return value | |
000ee07f JB |
183 | ;;;; is ignored. RESULT has one of the following forms: |
184 | ;;;; | |
57e7f270 DH |
185 | ;;;; pass - The test named TEST passed. |
186 | ;;;; Additional arguments are ignored. | |
187 | ;;;; upass - The test named TEST passed unexpectedly. | |
188 | ;;;; Additional arguments are ignored. | |
189 | ;;;; fail - The test named TEST failed. | |
190 | ;;;; Additional arguments are ignored. | |
191 | ;;;; xfail - The test named TEST failed, as expected. | |
192 | ;;;; Additional arguments are ignored. | |
193 | ;;;; unresolved - The test named TEST did not perform as expected, for | |
194 | ;;;; example the property that was to be tested could not be | |
195 | ;;;; tested because something else went wrong. | |
196 | ;;;; Additional arguments are ignored. | |
197 | ;;;; untested - The test named TEST was not actually performed, for | |
198 | ;;;; example because the test case is not complete yet. | |
199 | ;;;; Additional arguments are ignored. | |
200 | ;;;; unsupported - The test named TEST requires some feature that is not | |
201 | ;;;; available in the configured testing environment. | |
202 | ;;;; Additional arguments are ignored. | |
203 | ;;;; error - An error occurred while the test named TEST was | |
204 | ;;;; performed. Since this result means that the system caught | |
205 | ;;;; an exception it could not handle, the exception arguments | |
206 | ;;;; are passed as additional arguments. | |
000ee07f JB |
207 | ;;;; |
208 | ;;;; This library provides some standard reporters for logging results | |
209 | ;;;; to a file, reporting interesting results to the user, and | |
210 | ;;;; collecting totals. | |
087dab1c JB |
211 | ;;;; |
212 | ;;;; You can use the REGISTER-REPORTER function and friends to add | |
213 | ;;;; whatever reporting functions you like. If you don't register any | |
214 | ;;;; reporters, the library uses FULL-REPORTER, which simply writes | |
215 | ;;;; all results to the standard output. | |
