Increase test coverage to utils.dart

[victordmp]

Initial Proposed

• Improve test coverage to utils.dart on macOs.

My Proposed

• Improve the test suite coverage of filePathsToPlatformFiles().
  • Create two more test cases.
• Create test suite for runExecutableWithArguments() function.
  • There are no tests for it in file_picker_utils_test.dart.

Objective

• go from 52.2% coverage to 100% coverage for the utils file functions

Setup

• macOs Ventura 13.0

Fixes

Improve the test suite coverage of filePathsToPlatformFiles().

• Test 1:
  • Coverage Before:
  * **Added test case**

test(
    'should tranform a list of file paths containing a path into a list of PlatformFiles',
    () async {
  final filePaths = <String>['test'];

  final platformFiles = await filePathsToPlatformFiles(
    filePaths,
    true,
    false,
  );

  expect(platformFiles.length, equals(filePaths.length));
});

• Coverage After:
  

• Test 2:

  • Coverage Before:
  
  • Added test case

test(
    'should transform a list of file paths containing a valid path into a list of PlatformFiles',
    () async {
  final filePaths = <String>['test/test_files/test.pdf'];

  final platformFiles = await filePathsToPlatformFiles(
    filePaths,
    false,
    true,
  );

  expect(platformFiles.length, equals(filePaths.length));
});

• Coverage After:
  

Create test suite for runExecutableWithArguments() function.

• Coverage Before:

• Added test case

group('runExecutableWithArguments()', () {
  test('should catch an exception when sending an empty filepath', () async {
    final filepath = '';

    expect(
      () async => await isExecutableOnPath(filepath),
      throwsA(isA<Exception>()),
    );
  });
});

• Coverage After:
