[REFACTOR] Refactor Views Tests Setup to Use setUpTestData for Improved Performance

[Itz-Agasta]

Fixes #369

This PR refactors the TestViews class in test_views.py to use setUpTestData instead of setUp, significantly improving test performance by reducing redundant database operations.

Changes Made

• Refactored test data setup: Replaced setUp method with @classmethod setUpTestData(cls)
• Optimized database operations: Test data is now created once per test class instead of before every individual test
• Maintained test isolation: Ensured all tests continue to work correctly with shared test data
• Code quality improvements: Fixed linting issues and ensured full CI/CD compliance

Performance Benefits

Metric	Before (setUp)	After (setUpTestData)	Improvement
Test execution time	~0.30s	~0.25s	17% faster
Total runtime	~1.8s	~1.7s	6% faster
Database operations	195 objects (15×13)	15 objects (1×15)	92% reduction

Files Changed

• test_views.py

Hi @Lorygold ,

PR #389 had some merge conflicts, which I’ve resolved. As you mentioned, the related issue #369 for this PR is specifically focused on refactoring the Views tests. Since other methods are being handled in separate issues and PRs, i removed the file changes by me in alart/ this time.

That’s why I’ve opened this new PR.

Also, I ran the linters and formatters manually, and removed self.client in the function as you had pointed out in PR #389. Let me know if anything else needs to be adjusted!

Great @Itz-Agasta, I'll merge it!
