| 152 | " |
| 153 | " Note that the arguments of the following commands can be generated |
| 154 | " automatically, see below. |
| 155 | " |
| 156 | " Usage: {{{3 |
| 157 | " |
| 158 | " - Use XpathINIT at the beginning of the test. |
| 159 | " |
| 160 | " - Use Xpath to check if a line is executed. |
| 161 | " Argument: power of 2 (decimal). |
| 162 | " |
| 163 | " - To check multiple execution of loops use Xloop for automatically |
| 164 | " computing Xpath values: |
| 165 | " |
| 166 | " - Use XloopINIT before the loop. |
| 167 | " Two arguments: |
| 168 | " - the first Xpath value (power of 2) to be used (Xnext), |
| 169 | " - factor for computing a new Xnext value when reexecuting a loop |
| 170 | " (by a ":continue" or ":endwhile"); this should be 2^n where |
| 171 | " n is the number of Xloop commands inside the loop. |
| 172 | " If XloopINIT! is used, the first execution of XloopNEXT is |
| 173 | " a no-operation. |
| 174 | " |
| 175 | " - Use Xloop inside the loop: |
| 176 | " One argument: |
| 177 | " The argument and the Xnext value are multiplied to build the |
| 178 | " next Xpath value. No new Xnext value is prepared. The argument |
| 179 | " should be 2^(n-1) for the nth Xloop command inside the loop. |
| 180 | " If the loop has only one Xloop command, the argument can be |
| 181 | " ommitted (default: 1). |
| 182 | " |
| 183 | " - Use XloopNEXT before ":continue" and ":endwhile". This computes a new |
| 184 | " Xnext value for the next execution of the loop by multiplying the old |
| 185 | " one with the factor specified in the XloopINIT command. No Argument. |
| 186 | " Alternatively, when XloopINIT! is used, a single XloopNEXT at the |
| 187 | " beginning of the loop can be used. |
| 188 | " |
| 189 | " Nested loops are not supported. |
| 190 | " |
| 191 | " - Use Xcheck at end of each test. It prints the test number, the expected |
| 192 | " execution path value, the test result ("OK" or "FAIL"), and, if the tests |
| 193 | " fails, the actual execution path. |
| 194 | " One argument: |
| 195 | " Expected Xpath/Xloop sum for the correct execution path. |
| 196 | " In order that this value can be computed automatically, do the |
| 197 | " following: For each line in the test with an Xpath and Xloop |
| 198 | " command, add a comment starting with "X:" and specifying an |
| 199 | " expression that evaluates to the value contributed by this line to |
| 200 | " the correct execution path. (For copying an Xpath argument of at |
| 201 | " least two digits into the comment, press <C-P>.) At the end of the |
| 202 | " test, just type "Xcheck" and press <Esc>. |
| 203 | " |
| 204 | " - In order to add additional information to the test output file, use the |
| 205 | " Xout command. Argument(s) like ":echo". |
| 206 | " |
| 207 | " Automatic argument generation: {{{3 |
| 208 | " |
| 209 | " The arguments of the Xpath, XloopINIT, Xloop, and Xcheck commands can be |
| 210 | " generated automatically, so that new tests can easily be written without |
| 211 | " mental arithmetic. The Xcheck argument is computed from the "X:" comments |
| 212 | " of the preceding Xpath and Xloop commands. See the commands and |

| 9629 | " It is possible to configure Vim for throwing exceptions on error |
| 9630 | " or interrupt, controlled by variables $VIMNOERRTHROW and |
| 9631 | " $VIMNOINTTHROW. This is just for increasing the number of tests. |
| 9632 | " All tests here should run for all four combinations of setting |
| 9633 | " these variables to 0 or 1. The variables are intended for the |
| 9634 | " development phase only. In the final release, Vim should be |
| 9635 | " configured to always use error and interrupt exceptions. |
| 9636 | " |
| 9637 | " The test result is "OK", |
| 9638 | " |
| 9639 | " - if the $VIMNOERRTHROW and the $VIMNOINTTHROW control are not |
| 9640 | " configured and exceptions are thrown on error and on |
| 9641 | " interrupt. |
| 9642 | " |
| 9643 | " - if the $VIMNOERRTHROW or the $VIMNOINTTHROW control is |
| 9644 | " configured and works as intended. |
| 9645 | " |
| 9646 | " What actually happens, is shown in the test output. |
| 9647 | " |
| 9648 | " Otherwise, the test result is "FAIL", and the test output describes |
| 9649 | " the problem. |
| 9650 | " |
| 9651 | " IMPORTANT: This must be the last test because it sets $VIMNOERRTHROW and |
| 9652 | " $VIMNOINTTHROW. |
