77 | ;;;; CORE FUNCTIONS |
78 | ;;;; | |
79 | ;;;; The function (run-test name expected-result thunk) is the heart of the | |
80 | ;;;; testing environment. The first parameter NAME is a unique name for the | |
81 | ;;;; test to be executed (for an explanation of this parameter see below under | |
82 | ;;;; TEST NAMES). The second parameter EXPECTED-RESULT is a boolean value | |
83 | ;;;; that indicates whether the corresponding test is expected to pass. If | |
84 | ;;;; EXPECTED-RESULT is #t the test is expected to pass, if EXPECTED-RESULT is | |
85 | ;;;; #f the test is expected to fail. Finally, THUNK is the function that | |
86 | ;;;; actually performs the test. For example: | |
87 | ;;;; | |
88 | ;;;; (run-test "integer addition" #t (lambda () (= 2 (+ 1 1)))) | |
89 | ;;;; | |
90 | ;;;; To report success, THUNK should either return #t or throw 'pass. To | |
91 | ;;;; report failure, THUNK should either return #f or throw 'fail. If THUNK | |
92 | ;;;; returns a non boolean value or throws 'unresolved, this indicates that | |
93 | ;;;; the test did not perform as expected. For example the property that was | |
94 | ;;;; to be tested could not be tested because something else went wrong. | |
95 | ;;;; THUNK may also throw 'untested to indicate that the test was deliberately | |
96 | ;;;; not performed, for example because the test case is not complete yet. | |
97 | ;;;; Finally, if THUNK throws 'unsupported, this indicates that this test | |
98 | ;;;; requires some feature that is not available in the configured testing | |
99 | ;;;; environment. All other exceptions thrown by THUNK are considered as | |
100 | ;;;; errors. | |

103 | ;;;; Convenience macros for tests expected to pass or fail | |
104 | ;;;; | |
bba2d190 | 105 | ;;;; * (pass-if name body) is a short form for |
57e7f270 | 106 | ;;;; (run-test name #t (lambda () body)) |
bba2d190 | 107 | ;;;; * (expect-fail name body) is a short form for |
57e7f270 DH |
108 | ;;;; (run-test name #f (lambda () body)) |
109 | ;;;; | |
bba2d190 | 110 | ;;;; For example: |
57e7f270 DH |

114 | ;;;; | |
115 | ;;;; Convenience macros to test for exceptions | |
116 | ;;;; | |
117 | ;;;; The following macros take exception parameters which are pairs | |
118 | ;;;; (type . message), where type is a symbol that denotes an exception type | |
119 | ;;;; like 'wrong-type-arg or 'out-of-range, and message is a string holding a | |
120 | ;;;; regular expression that describes the error message for the exception | |
121 | ;;;; like "Argument .* out of range". | |
122 | ;;;; | |
123 | ;;;; * (pass-if-exception name exception body) will pass if the execution of | |
124 | ;;;; body causes the given exception to be thrown. If no exception is | |
b3da54d1 | 125 | ;;;; thrown, the test fails. If some other exception is thrown, it is an |
6b4113af DH |
126 | ;;;; error. |
127 | ;;;; * (expect-fail-exception name exception body) will pass unexpectedly if | |
128 | ;;;; the execution of body causes the given exception to be thrown. If no | |
129 | ;;;; exception is thrown, the test fails expectedly. If some other | |
130 | ;;;; exception is thrown, it is an error. | |

133 | ;;;; TEST NAMES |
134 | ;;;; | |
135 | ;;;; Every test in the test suite has a unique name, to help | |
136 | ;;;; developers find tests that are failing (or unexpectedly passing), | |
137 | ;;;; and to help gather statistics. | |
138 | ;;;; | |
139 | ;;;; A test name is a list of printable objects. For example: | |
140 | ;;;; ("ports.scm" "file" "read and write back list of strings") | |
141 | ;;;; ("ports.scm" "pipe" "read") | |
142 | ;;;; | |
143 | ;;;; Test names may contain arbitrary objects, but they always have | |
144 | ;;;; the following properties: | |
145 | ;;;; - Test names can be compared with EQUAL?. | |
146 | ;;;; - Test names can be reliably stored and retrieved with the standard WRITE | |
147 | ;;;; and READ procedures; doing so preserves their identity. | |
bba2d190 | 148 | ;;;; |
000ee07f | 149 | ;;;; For example: |
bba2d190 | 150 | ;;;; |
57e7f270 | 151 | ;;;; (pass-if "simple addition" (= 4 (+ 2 2))) |
bba2d190 | 152 | ;;;; |
000ee07f JB |
153 | ;;;; In that case, the test name is the list ("simple addition"). |
154 | ;;;; | |
e46083d5 DH |
155 | ;;;; In the case of simple tests the expression that is tested would often |
156 | ;;;; suffice as a test name by itself. Therefore, the convenience macros | |
157 | ;;;; pass-if and expect-fail provide a shorthand notation that allows to omit | |
158 | ;;;; a test name in such cases. | |
159 | ;;;; | |
160 | ;;;; * (pass-if expression) is a short form for | |
161 | ;;;; (run-test 'expression #t (lambda () expression)) | |
162 | ;;;; * (expect-fail expression) is a short form for | |
163 | ;;;; (run-test 'expression #f (lambda () expression)) | |
164 | ;;;; | |
165 | ;;;; For example: | |
166 | ;;;; | |
167 | ;;;; (pass-if (= 2 (+ 1 1))) | |
168 | ;;;; | |
000ee07f JB |
169 | ;;;; The WITH-TEST-PREFIX syntax and WITH-TEST-PREFIX* procedure establish |
170 | ;;;; a prefix for the names of all tests whose results are reported | |
171 | ;;;; within their dynamic scope. For example: | |
bba2d190 | 172 | ;;;; |
000ee07f JB |
173 | ;;;; (begin |
174 | ;;;; (with-test-prefix "basic arithmetic" | |
175 | ;;;; (pass-if "addition" (= (+ 2 2) 4)) | |
05c4ba00 | 176 | ;;;; (pass-if "subtraction" (= (- 4 2) 2))) |
000ee07f | 177 | ;;;; (pass-if "multiplication" (= (* 2 2) 4))) |
bba2d190 | 178 | ;;;; |
000ee07f JB |
179 | ;;;; In that example, the three test names are: |
180 | ;;;; ("basic arithmetic" "addition"), | |
05c4ba00 | 181 | ;;;; ("basic arithmetic" "subtraction"), and |
000ee07f JB |
182 | ;;;; ("multiplication"). |
183 | ;;;; | |
679cceed | 184 | ;;;; WITH-TEST-PREFIX can be nested. Each WITH-TEST-PREFIX appends |
000ee07f | 185 | ;;;; a new element to the current prefix: |
bba2d190 | 186 | ;;;; |
000ee07f JB |
187 | ;;;; (with-test-prefix "arithmetic" |
188 | ;;;; (with-test-prefix "addition" | |
189 | ;;;; (pass-if "integer" (= (+ 2 2) 4)) | |
190 | ;;;; (pass-if "complex" (= (+ 2+3i 4+5i) 6+8i))) | |
191 | ;;;; (with-test-prefix "subtraction" | |
192 | ;;;; (pass-if "integer" (= (- 2 2) 0)) | |
193 | ;;;; (pass-if "complex" (= (- 2+3i 1+2i) 1+1i)))) | |
bba2d190 | 194 | ;;;; |
000ee07f JB |
195 | ;;;; The four test names here are: |
196 | ;;;; ("arithmetic" "addition" "integer") | |
197 | ;;;; ("arithmetic" "addition" "complex") | |
198 | ;;;; ("arithmetic" "subtraction" "integer") | |
199 | ;;;; ("arithmetic" "subtraction" "complex") | |
200 | ;;;; | |
201 | ;;;; To print a name for a human reader, we DISPLAY its elements, | |
202 | ;;;; separated by ": ". So, the last set of test names would be | |
203 | ;;;; reported as: | |
bba2d190 | 204 | ;;;; |
000ee07f JB |
205 | ;;;; arithmetic: addition: integer |
206 | ;;;; arithmetic: addition: complex | |
207 | ;;;; arithmetic: subtraction: integer | |
208 | ;;;; arithmetic: subtraction: complex | |
209 | ;;;; | |
210 | ;;;; The Guile benchmarks use with-test-prefix to include the name of | |
211 | ;;;; the source file containing the test in the test name, to help | |
212 | ;;;; developers to find failing tests, and to provide each file with its | |
213 | ;;;; own namespace. | |

216 | ;;;; REPORTERS | |
bba2d190 | 217 | ;;;; |
000ee07f JB |
218 | ;;;; A reporter is a function which we apply to each test outcome. |
219 | ;;;; Reporters can log results, print interesting results to the | |
220 | ;;;; standard output, collect statistics, etc. | |
bba2d190 | 221 | ;;;; |
57e7f270 DH |
222 | ;;;; A reporter function takes two mandatory arguments, RESULT and TEST, and |
223 | ;;;; possibly additional arguments depending on RESULT; its return value | |
000ee07f JB |
224 | ;;;; is ignored. RESULT has one of the following forms: |
225 | ;;;; | |
bba2d190 | 226 | ;;;; pass - The test named TEST passed. |
57e7f270 DH |
227 | ;;;; Additional arguments are ignored. |
228 | ;;;; upass - The test named TEST passed unexpectedly. | |
229 | ;;;; Additional arguments are ignored. | |
230 | ;;;; fail - The test named TEST failed. | |
231 | ;;;; Additional arguments are ignored. | |
232 | ;;;; xfail - The test named TEST failed, as expected. | |
233 | ;;;; Additional arguments are ignored. | |
234 | ;;;; unresolved - The test named TEST did not perform as expected, for | |
235 | ;;;; example the property that was to be tested could not be | |
236 | ;;;; tested because something else went wrong. | |
237 | ;;;; Additional arguments are ignored. | |
238 | ;;;; untested - The test named TEST was not actually performed, for | |
bba2d190 | 239 | ;;;; example because the test case is not complete yet. |
57e7f270 DH |
240 | ;;;; Additional arguments are ignored. |
241 | ;;;; unsupported - The test named TEST requires some feature that is not | |
242 | ;;;; available in the configured testing environment. | |
243 | ;;;; Additional arguments are ignored. | |
244 | ;;;; error - An error occurred while the test named TEST was | |
245 | ;;;; performed. Since this result means that the system caught | |
246 | ;;;; an exception it could not handle, the exception arguments | |
247 | ;;;; are passed as additional arguments. | |
000ee07f JB |
248 | ;;;; |
249 | ;;;; This library provides some standard reporters for logging results | |
250 | ;;;; to a file, reporting interesting results to the user, and | |
251 | ;;;; collecting totals. | |
087dab1c JB |
252 | ;;;; |
253 | ;;;; You can use the REGISTER-REPORTER function and friends to add | |
254 | ;;;; whatever reporting functions you like. If you don't register any | |
255 | ;;;; reporters, the library uses FULL-REPORTER, which simply writes | |
256 | ;;;; all results to the standard output. | |
