DESCRIPTION: This module tests that the functions related to workstation generate the specified workstation error messages if they are executed in incorrect conditions. The error is handled by a default system error handling subroutine. Also, this module tests the requirement that no side effects are generated. SEMANTIC REQUIREMENTS:#F 3
SR1. If function <open workstation> is called, and the specified connection identifier is not recognized by the implementation, then error 50 or 55 is generated and the function is ignored.
#F 3
SR2. If function <open workstation> is called, and the specified workstation type is not recongnized by the implementation, then error 52 or 55 is generated and the function is ignored.
#F 3
SR3. If function <open workstation> is called, and the specified workstation identifier already is in use, then error 53 is generated and the function is ignored.
#F 4-8 63-72 74 84-90 132-134 151-185 187 196-198
SR4. If functions <close workstation>-<messages>, <set polyline representation>-<set colour model>, <set hlhsr mode>, <set view representation 3>-<set workstation viewport>, <post structure>-<unpost all structures>, <set pick filter>-<sample string>, <flush device events>, <write item to metafile>- <read item from metafile> are called , and the specified workstation is not open, then error 54 or 3 is generated and the function is ignored.
#F 3
SR5. If function <open workstation> is called, and the specified workstation cannot be opened for an implementation reason, then error 55, 50 or 52 is generated and the function is ignored.
#F 196
SR6. If function <write item to metafile> is called, and the specified workstation is not of category MO, then error 56 is generated and the function is ignored.
#F 84-90
SR7. If functions <set view representation 3>-<set workstation viewport> are called, and the specified workstation is of category MI, then error 57 is generated and the function is ignored.
#F 197-198
SR8. If functions <get item type from metafile>-<read item from metafile> are called, and the specified workstation is not of category MI, then error 58 is generated and the function is ignored.
#F 5-7 63-72 74 132-134
SR9. If functions <redraw all structures>-<set display update state>, <set polyline representation>-<set colour mode>, <set hlhsr filter>, <post stucture>-<unpost all structures> are called, and the specified workstation does not have output capability, then error 59 is generated and the function is ignored.
#F 151 160 161 168 173 176 184
SR10. If functions <set pick filter>, <initialize pick 3>, <initialize pick>, <set pick mode>, <request stroke>, <request pick>, <sample pick> are called, and the specified workstation is not of category OUTIN, then error 60 is generated and the function is ignored.
#F 152-159 162-167 169-172 174 175 177-183 185 187
SR11. If functions <initialize locator 3>-<initialize choice>, <intialize string 3>-<set choice mode>, <set string mode>-<request stroke 3>, <request valuator>, <request choice>, <request string>-<sample choice>, <sample string>, <flush device events> are called, and the specified workstation is neither of category INPUT nor of category OUTIN, then error 61 is generated and the function is ignored.
#F 3
SR12. If function <open workstation> is called, and opening this workstation would exceed the maximum number of simultaneously open workstation, then error 63 is generated and the function is ignored.
