Improve Test Coverage

[varshith257]

Purpose

This PR aims to increase the test coverage of the StarbaseDB project to 75%+ using Vitest. The improvements ensure meaningful tests that not only improve line coverage but also help detect potential issues by testing different scenarios and edge cases and fixed few of them too

Tasks

• Added unit tests

• Fixed found issues too

• [ ]

Verify

• Run the test suite using:

pnpm vitest run --coverage

• Confirm that all tests pass and coverage has increased

@Brayden PTAL. I will test each function cleanly, push the code from on and have fixed few issues found too

[varshith257]

@Brayden Test coverage is good so far and few issues have been found in the DELETE operation so I have commented. I will take a close look fix it and improve some more files' test coverage to reach ~85-90

[varshith257]

@Brayden It's weekend and I am out . I will push final remaining changes by tomorrow

[Brayden]

@varshith257 No worries. I was just updating your PR so it didn't have merge conflicts. I introduced a couple test changes so a report could be displayed on new PR's. I ran the test coverage here and figured I'd share:

Also do you recall what error you were getting for DELETE operations? Curious to what bug was uncovered!

@Brayden I can't remember what exactly found as I kept in a notes in my desktop but what i remember is it throwing bad request instead executing delete operation

For example check this

        // it('should handle DELETE requests successfully', async () => { 
         //     vi.mocked(executeQuery).mockImplementation(async ({ sql }) => { 
         //         console.log('Mock executeQuery called with:', sql) 
  
         //         if (sql.includes('PRAGMA table_info(users)')) { 
         //             return [{ name: 'id', pk: 1 }] 
         //         } 
  
         //         return [] 
         //     }) 
         //     vi.mocked(executeTransaction).mockResolvedValue([]) 
  
         //     const request = new Request('http://localhost/rest/users/1', { 
         //         method: 'DELETE', 
         //     }) 
         //     const response = await liteRest.handleRequest(request) 
  
         //     console.log('DELETE Test Response:', response) 
  
         //     expect(response).toBeInstanceOf(Response) 
         //     expect(response.status).toBe(200) 
  
         //     const jsonResponse = (await response.json()) as { 
         //         result: { message: string } 
         //     } 
         //     console.log('Parsed JSON Response:', jsonResponse) 
  
         //     expect(jsonResponse.result).toEqual({ 
         //         message: 'Resource deleted successfully', 
         //     }) 
         // })

and this too

        // it('should return 400 for DELETE without ID', async () => { 
         //     const request = new Request('http://localhost/rest/users', { 
         //         method: 'DELETE', 
         //     }) 
         //     const response = await liteRest.handleRequest(request) 
  
         //     expect(response).toBeInstanceOf(Response) 
         //     expect(response.status).toBe(400) 
  
         //     const jsonResponse = (await response.json()) as { error: string } 
         //     expect(jsonResponse.error).toBe( 
         //         "Missing primary key value for 'id'" 
         //     ) 
         // }) 
 

It throwing 500 instead 400 above and delete query succes. I need to go another round of their implementation to validate whether I am wrongly testing the method or need a fix there. To capitalise i have commented and just console logged their results but here mock data receiving perfectly to the DELTE but when executed final result is getting undefined

@varshith257 Wanted to check in and see if you had more ready to push up or not! :)

[varshith257]

@Brayden Sorry for the inconvenience. Actually I had on holiday from last 3 days so didn't push changes here. I am back and on the work
