/* Nix evaluation tests for various lib functions. Since these tests are implemented with Nix evaluation, error checking is limited to what `builtins.tryEval` can detect, which is `throw`'s and `abort`'s, without error messages. If you need to test error messages or more complex evaluations, see ./modules.sh, ./sources.sh or ./filesystem.sh as examples. To run these tests: [nixpkgs]$ nix-instantiate --eval --strict lib/tests/misc.nix If the resulting list is empty, all tests passed. Alternatively, to run all `lib` tests: [nixpkgs]$ nix-build lib/tests/release.nix */ with import ../default.nix; let testingThrow = expr: { expr = (builtins.tryEval (builtins.seq expr "didn't throw")); expected = { success = false; value = false; }; }; testingEval = expr: { expr = (builtins.tryEval expr).success; expected = true; }; testingDeepThrow = expr: testingThrow (builtins.deepSeq expr expr); testSanitizeDerivationName = { name, expected }: let drv = derivation { name = strings.sanitizeDerivationName name; builder = "x"; system = "x"; }; in { # Evaluate the derivation so an invalid name would be caught expr = builtins.seq drv.drvPath drv.name; inherit expected; }; in runTests { # CUSTOMIZATION testFunctionArgsMakeOverridable = { expr = functionArgs (makeOverridable ({ a, b, c ? null}: {})); expected = { a = false; b = false; c = true; }; }; testFunctionArgsMakeOverridableOverride = { expr = functionArgs (makeOverridable ({ a, b, c ? null }: {}) { a = 1; b = 2; }).override; expected = { a = false; b = false; c = true; }; }; # TRIVIAL testId = { expr = id 1; expected = 1; }; testConst = { expr = const 2 3; expected = 2; }; testPipe = { expr = pipe 2 [ (x: x + 2) # 2 + 2 = 4 (x: x * 2) # 4 * 2 = 8 ]; expected = 8; }; testPipeEmpty = { expr = pipe 2 []; expected = 2; }; testPipeStrings = { expr = pipe [ 3 4 ] [ (map toString) (map (s: s + "\n")) concatStrings ]; expected = '' 3 4 ''; }; /* testOr = { expr = or true false; expected = true; }; */ testAnd = { expr = and true false; expected = false; }; testFix = { expr = fix (x: {a = if x ? a then "a" else "b";}); expected = {a = "a";}; }; testComposeExtensions = { expr = let obj = makeExtensible (self: { foo = self.bar; }); f = self: super: { bar = false; baz = true; }; g = self: super: { bar = super.baz or false; }; f_o_g = composeExtensions f g; composed = obj.extend f_o_g; in composed.foo; expected = true; }; testComposeManyExtensions0 = { expr = let obj = makeExtensible (self: { foo = true; }); emptyComposition = composeManyExtensions []; composed = obj.extend emptyComposition; in composed.foo; expected = true; }; testComposeManyExtensions = let f = self: super: { bar = false; baz = true; }; g = self: super: { bar = super.baz or false; }; h = self: super: { qux = super.bar or false; }; obj = makeExtensible (self: { foo = self.qux; }); in { expr = let composition = composeManyExtensions [f g h]; composed = obj.extend composition; in composed.foo; expected = (obj.extend (composeExtensions f (composeExtensions g h))).foo; }; testBitAnd = { expr = (bitAnd 3 10); expected = 2; }; testBitOr = { expr = (bitOr 3 10); expected = 11; }; testBitXor = { expr = (bitXor 3 10); expected = 9; }; testToHexString = { expr = toHexString 250; expected = "FA"; }; testToBaseDigits = { expr = toBaseDigits 2 6; expected = [ 1 1 0 ]; }; testFunctionArgsFunctor = { expr = functionArgs { __functor = self: { a, b }: null; }; expected = { a = false; b = false; }; }; testFunctionArgsSetFunctionArgs = { expr = functionArgs (setFunctionArgs (args: args.x) { x = false; }); expected = { x = false; }; }; # STRINGS testConcatMapStrings = { expr = concatMapStrings (x: x + ";") ["a" "b" "c"]; expected = "a;b;c;"; }; testConcatStringsSep = { expr = concatStringsSep "," ["a" "b" "c"]; expected = "a,b,c"; }; testConcatLines = { expr = concatLines ["a" "b" "c"]; expected = "a\nb\nc\n"; }; testReplicateString = { expr = strings.replicate 5 "hello"; expected = "hellohellohellohellohello"; }; testSplitStringsSimple = { expr = strings.splitString "."
