A typecheck failed because test globals were unknown, and the compiler message pointed at installing Jest type definitions. I added @types/jest 29.5.14, on the same major line as the runner. The following no-emit typecheck completed successfully.
What worked
The package matched the Jest 29 types the compiler asked for, and installing it cleared the missing-name errors on the next typecheck.

Typechecking test assertions
I installed @types/jest 29.5.14 with the test runner so TypeScript tests could use Jest matchers. Assertions such as property and containment checks compiled, and the suite passed on the following runs. No matcher type mismatches showed up.
What worked
The 29.5.14 types matched Jest 29 and the matchers used in the billing tests. Install was a single dev dependency and needed no extra configuration.

Type-checking Jest test suites
The Jest type declarations supplied the missing TypeScript definitions for test globals. Installing version 29.5.14 resolved all reported errors for functions such as test cases and assertions, after which the build passed.
What worked
The compiler errors directly indicated the missing package, and adding it fixed the type-checking problem without source changes.
What got in the way
It was absent from the original development dependencies even though test files were included in the TypeScript build.

Type-checking Jest test suites
Jest type definitions were installed to provide TypeScript declarations for test globals such as the test function and assertions. This directly resolved the compiler errors shown in the test files.
What worked
Installing the package fixed the missing-global diagnostics without requiring source-level declarations or compiler workarounds.
What got in the way
It was missing from the original development dependencies even though TypeScript compiled the Jest test files.

Type-checking the Jest test suite
Installed the Jest type declarations after TypeScript reported unresolved test globals such as test cases and assertions. Adding the package eliminated those compiler errors and allowed the build to pass.
What worked
The package directly fixed the compiler errors identified in the recorded build output.
What got in the way
The declarations were missing from the initial project installation, causing the first compilation attempt to fail.

Type-checking Jest test suites
Installed the Jest type definitions required by the TypeScript test setup. They worked with the selected Jest and ts-jest versions, and both compilation and all tests passed.
What worked
The exact version installed cleanly and supplied the test globals and matcher types needed by the suite.
What got in the way
The package was missing from the original development dependencies and had to be added explicitly.

Type-checking Jest test files
The Jest type definitions were installed after TypeScript reported unresolved test globals. They resolved the compiler errors without further recorded configuration changes, and subsequent builds and tests passed.

Type-checking Jest test globals
Installed the Jest declaration package after TypeScript reported missing test globals such as test cases and expectations. The declarations resolved the recorded compile errors, and the final build succeeded.

The compiler's suggested package was the correct targeted fix for all reported missing Jest globals.

Type-checking Jest test files
Installed Jest type definitions after TypeScript reported unknown test globals such as test cases and expectations. The next build succeeded, resolving all seventeen reported type errors.

Type-checking Jest test files
The Jest type definitions at version 29.5.14 supplied the missing describe, it, and expect globals. Installing them resolved the initial TypeScript build errors and subsequent builds passed.

The compiler's suggested package was the correct fix, and no further typing workaround was needed.

Providing Jest globals to the TypeScript compiler
The Jest type definitions were installed after TypeScript reported unresolved test globals. They directly resolved the compilation blocker and the final build passed.
What worked
The package supplied the expected definitions for test functions and assertions with no further recorded type errors.

Providing Jest globals to TypeScript tests
The Jest declaration package was installed directly to provide TypeScript definitions for test globals such as describe, it, and expect.
What worked
Installing the declarations resolved the missing-global diagnostics for the test compilation path.
What got in the way
The package was absent from the original repository even though TypeScript test files and a Jest configuration were present, contributing to the first build failure.
