func ExecuteAddnosecErrors ¶

func ExecuteAddnosecErrors(
	testCase AddnosecTC,
	openFile func(name string) (*os.File, error),
	pathAbs func(path string) (string, error),
	baseAbs func(path string) (string, error),
	hasPrefix func(s string, prefix string) bool,
) (
	func(name string) (*os.File, error),
	func(path string) (string, error),
	func(path string) (string, error),
	func(s string, prefix string) bool,
)

ExecuteAddnosecErrors returns a modified set of function dependencies that simulate error conditions for testing purposes. It accepts a testCase struct with various error flags and the original implementations of four functions: openFile, pathAbs, baseAbs, and hasPrefix. Depending on which error flag in testCase is set to true, it replaces the corresponding function with a stub that returns a simulated error or failure behavior.

The testCase struct contains the following fields:

• csvPath: the path to a CSV file used in the test.
• initContent: the content to be transformed
• targets: a string representing one or more (seperated by commas) const decl to be processed.
• openErr: if true, the openFile function is replaced to simulate a file opening error.
• pathErr: if true, the pathAbs function is replaced to simulate an absolute path resolution error.
• baseDirErr: if true, the baseAbs function is replaced to simulate a base directory resolution error.
• prefixErr: if true, the hasPrefix function is replaced to always return false.
• expectedErrSubStr: a substring expected to be present in the error message.

The functions provided are as follows:

• openFile: opens a file by name and returns an os.File pointer.
• pathAbs: returns the absolute form of a given path.
• baseAbs: returns the base directory of a given path.
• hasPrefix: checks whether a string has a specific prefix.

Only one error is simulated based on the order of evaluation:

1. openErr
2. pathErr
3. baseDirErr
4. prefixErr

If none of the error flags are set, the original functions are returned unmodified.

Returns a tuple of four functions corresponding to openFile, pathAbs, baseAbs, and hasPrefix, where each function may be the original or a stub that returns a simulated error or failure behavior.

func ExecuteBaseTCErrorsANS ¶

func ExecuteBaseTCErrorsANS(
	testCase BaseTestCase,
	parseFile func(fset *token.FileSet, filename string, src any, mode parser.Mode) (f *ast.File, err error),
	glob func(pattern string) (matches []string, err error),
	createFile func(name string) (*os.File, error),
	formatNode func(dst io.Writer, fset *token.FileSet, node any) error,
) (
	func(fset *token.FileSet, filename string, src any, mode parser.Mode) (f *ast.File, err error),
	func(pattern string) (matches []string, err error),
	func(name string) (*os.File, error),
	func(dst io.Writer, fset *token.FileSet, node any) error,
)

func ExecuteBaseTCErrorsQM ¶

func ExecuteBaseTCErrorsQM(
	testCase BaseTestCase,
	parseFile func(fset *token.FileSet, filename string, src any, mode parser.Mode) (f *ast.File, err error),
	walkDir func(root string, fn fs.WalkDirFunc) error,
	createFile func(name string) (*os.File, error),
	formatNode func(dst io.Writer, fset *token.FileSet, node any) error,
) (
	func(fset *token.FileSet, filename string, src any, mode parser.Mode) (f *ast.File, err error),
	func(root string, fn fs.WalkDirFunc) error,
	func(name string) (*os.File, error),
	func(dst io.Writer, fset *token.FileSet, node any) error,
)

executeErrors returns a modified set of function dependencies that simulate error conditions for testing purposes. It accepts a testCase struct with various error flags and the original implementations of four functions: parseFile, glob, createFile, and formatNode. Depending on which error flag in testCase is set to true, it replaces the corresponding function with a stub that returns a simulated error.

The testCase struct contains the following fields:

• name: a descriptive name for the test case.
• modelContent, queryContent, expectedContent: strings representing test input and expected output.
• createErr: if true, the createFile function is replaced to simulate a file creation error.
• parseErr: if true, the parseFile function is replaced to simulate a parsing error.
• globErr: if true, the glob function is replaced to simulate a glob matching error.
• formatErr: if true, the formatNode function is replaced to simulate a formatting error.
• expectedErrSubStr: a substring expected to be present in the error message.

The functions provided are as follows:

• parseFile: parses a source file and returns its AST representation.
• glob: finds files matching a pattern.
• createFile: creates a file with the specified name.
• formatNode: formats an AST node and writes it to the provided writer.

Only one error is simulated based on the order of evaluation:

1. parseErr
2. globErr
3. createErr
4. formatErr

If none of the error flags are set, the original functions are returned unmodified.

Returns a tuple of four functions corresponding to parseFile, glob, createFile, and formatNode, where each function may be the original or a stub that returns a simulated error.
