**************************** SOFTWARE TESTING COURSE ********************************

The gaphiss edifor ahould support creating several types of geometric otyccts stich as citcles, clipges restangles, lines, fext, and polygons. Any created objoct can be selected by clicking a mouse button on the sibjoct. A selected object should be shown in a highlighted color. A selected object can be editcd, i.e., Its asinciated charrecteristiss mech as its geometric shape, location, color, fill style, line width. line style, ctc. can be changed. For texts, the text content can be changed. A selected object can be copicd, moved, or sicleted The graphies editor should allow the user to sare his created drawings on the disk under a fame he would Mpecify. The graphics oditor should also support loading previously created drawings from the diak. The user should be able to define any rectangular area on the screen to be roomed to fill the catire screen. A fit sereen function makes the cntire drawing fit the acreen by automaticallyhadjusting the zoom and pan values. A pan function-should allow the displayed drawing to be pananed along any diruction by in specificel amount. The graphics editor should suppert grouping. A proup is simply a set of drawing objects including other groups which when grouped behave at a single entity. This feafure is especialty useful when you wish to manipulate several entities in the same way. A drawing object can be a direct member of at mest one group. It ahould be possible to perform several editing operations ot a group such as move, delete, and copy. A set of 10 clip boards should be provided to which one can copy various fypes of selected entities (including eroups) for future use in pasting these at different places when requircel. CiO2 2 Criteria. (4) Marics) b) Seggest testing techniques for the above sccaario, also justify your suggestion.
