Autotests: Display molecules in macro mode: basic structures with atoms and bonds

[AlexeyGirin]

Source task(s):

• Display molecules in macro mode: basic structures with atoms and bonds #5359

• Verify that all types of bonds (single, double, triple) are correctly displayed in macro mode

• Verify that carbon atoms are not displayed in macro mode, but hydrogen atoms are displayed with a subscript showing valence

• Verify that hydrogen labels appear correctly before or after the atom label when valence exceeds the number of connections in macro mode

• Verify that connection points between monomers and molecules can be created by drawing bonds in macro mode

• Verify that bond lines between atoms do not overlap in any angle in macro mode

• Verify that connections between monomers and molecules are maintained correctly in both micro and macro modes

• Verify that switching between micro and macro modes displays molecules without structural changes

• Verify that bonds between atoms appear with correct lengths and angles when displayed in macro mode

• Verify that deleting an atom in macro mode removes it along with all connected bonds without distorting the molecule structure

• Verify that deleting a bond in macro mode removes the bond while maintaining the integrity of the surrounding structure

• Verify that the Undo tool restores an atom deleted in macro mode to its original position, along with all connected bonds

• Verify that the Redo tool re-applies an atom or bond deletion after an Undo operation in macro mode

• Verify that deleting a group of atoms and bonds in macro mode can be undone, and the entire group is restored to its original state

• Verify that after Undo, the structure's bonds and atoms return to their exact original position without any loss of integrity

• Verify that the structure in macro mode can be saved as a .ket file, and all elements including bonds and atoms are correctly restored when re-loaded

• Verify that the structure in macro mode can be saved as a .mol file, and upon re-loading, all atoms and bonds are correctly displayed

• Verify that the structure in macro mode can be saved as a (Sequence, FASTA, IDT, SVG, HELM) file, and upon re-loading, all atoms and bonds are correctly displayed

• Verify that a selection of atoms and bonds in macro mode can be copied and pasted to a new location on the canvas

• Verify that after copying a selection in macro mode, pasting it multiple times places the structure correctly at each new location

• Verify that a selection of atoms and bonds in macro mode can be cut and pasted to a new location on the canvas, and the original structure is removed

• Verify that after cutting a selection in macro mode, undoing the operation restores the original structure to its initial location

• Verify that after pasting a copied or cut structure, undoing the operation removes the newly placed structure

• Verify that a pasted structure can be reselected and further copied or cut to a new location

• Verify that using the "Ctrl+X" (Cut), "Ctrl+C" (Copy), and "Ctrl+V" (Paste) shortcuts in macro mode works as expected

• Verify that after copying or cutting a selection of atoms and bonds in macro mode, the pasted structure retains the same connections and labels

• Verify that copy and paste operations work for circular macromolecular structures without distorting the bonds or atoms
