// You are a professional Java test case writer, please create a test case named `testStringJoinAdd` for the issue `Closure-106`, utilizing the provided issue report information and the following function signature. // ## Issue-ID: Closure-106 // // ## Issue-Title: // Array Join Munged Incorrectly // // ## Issue-Description: // $.fn.hasClass = function(selector) { // return ( this.length > 0 ? // !( ( ['', this[0].className, ''].join(' ') ).indexOf( ['', selector, // ''].join(' ') ) == -1 ) // : false ); // }; // // munges into // // $.fn.hasClass=function(a){return this.length>0? // (""+this[0].className).indexOf(""+a)!=-1:false}; // // which is not identical. Looks like there might be an issue with join and ' '. // //

```markdown ## Issue-ID: Math-MATH-338 ## Issue-Title: Wrong parameter for first step size guess for Embedded Runge Kutta methods ## Issue-Description: In a space application using DOP853 i detected what seems to be a bad parameter in the call to the method initializeStep of class AdaptiveStepsizeIntegrator. Here, DormandPrince853Integrator is a subclass for EmbeddedRungeKuttaIntegrator which perform the call to initializeStep at the beginning of its method integrate(...) The problem comes from the array "scale" that is used as a parameter in the call off initializeStep(..) Following the theory described by Hairer in his book "Solving Ordinary Differential Equations 1 : Nonstiff Problems", the scaling should be : sci = Atol i + |y0i| \* Rtoli Whereas EmbeddedRungeKuttaIntegrator uses : sci = Atoli Note that the Gragg-Bulirsch-Stoer integrator uses the good implementation "sci = Atol i + |y0i| \* Rtoli " when he performs the call to the same method initializeStep(..) In the method initializeStep, the error leads to a wrong step size h used to perform an Euler step. Most of the time it is unvisible for the user. But in my space application the Euler step with this wrong step size h (much bigger than it should be) makes an exception occur (my satellite hits the ground...) To fix the bug, one should use the same algorithm as in the rescale method in GraggBulirschStoerIntegrator For exemple : final double[] scale= new double[y0.length];; if (vecAbsoluteTolerance == null) { for (int i = 0; i < scale.length; ++i) { final double yi = Math.max(Math.abs(y0[i]), Math.abs(y0[i])); scale[i] = scalAbsoluteTolerance + scalRelativeTolerance \* yi; } } else { for (int i = 0; i < scale.length; ++i) { final double yi = Math.max(Math.abs(y0[i]), Math.abs(y0[i])); scale[i] = vecAbsoluteTolerance[i] + vecRelativeTolerance[i] \* yi; } } hNew = initializeStep(equations, forward, getOrder(), scale, stepStart, y, yDotK[0], yTmp, yDotK[1]); Sorry for the length of this message, looking forward to hearing from you soon Vincent Morand ``` You are a professional Java test case writer, please create a test case named `polynomial` for the issue `Math-MATH-338`, utilizing the provided issue report information and the following function signature. ```java @Test public void polynomial() throws DerivativeException, IntegratorException { ```

// You are a professional Java test case writer, please create a test case named `polynomial` for the issue `Math-MATH-338`, utilizing the provided issue report information and the following function signature. // ## Issue-ID: Math-MATH-338 // // ## Issue-Title: // Wrong parameter for first step size guess for Embedded Runge Kutta methods // // ## Issue-Description: // // In a space application using DOP853 i detected what seems to be a bad parameter in the call to the method initializeStep of class AdaptiveStepsizeIntegrator. // // // Here, DormandPrince853Integrator is a subclass for EmbeddedRungeKuttaIntegrator which perform the call to initializeStep at the beginning of its method integrate(...) // // // The problem comes from the array "scale" that is used as a parameter in the call off initializeStep(..) // // // Following the theory described by Hairer in his book "Solving Ordinary Differential Equations 1 : Nonstiff Problems", the scaling should be : // // // sci = Atol i + |y0i| \* Rtoli // // // Whereas EmbeddedRungeKuttaIntegrator uses : sci = Atoli // // // Note that the Gragg-Bulirsch-Stoer integrator uses the good implementation "sci = Atol i + |y0i| \* Rtoli " when he performs the call to the same method initializeStep(..) // // // In the method initializeStep, the error leads to a wrong step size h used to perform an Euler step. Most of the time it is unvisible for the user. // // But in my space application the Euler step with this wrong step size h (much bigger than it should be) makes an exception occur (my satellite hits the ground...) // // // To fix the bug, one should use the same algorithm as in the rescale method in GraggBulirschStoerIntegrator // // For exemple : // // // final double[] scale= new double[y0.length];; // // // if (vecAbsoluteTolerance == null) { // // for (int i = 0; i < scale.length; ++i) // // // { // final double yi = Math.max(Math.abs(y0[i]), Math.abs(y0[i])); // scale[i] = scalAbsoluteTolerance + scalRelativeTolerance \* yi; // } // } else { // // for (int i = 0; i < scale.length; ++i) // // // { // final double yi = Math.max(Math.abs(y0[i]), Math.abs(y0[i])); // scale[i] = vecAbsoluteTolerance[i] + vecRelativeTolerance[i] \* yi; // } // } // // // hNew = initializeStep(equations, forward, getOrder(), scale, // // stepStart, y, yDotK[0], yTmp, yDotK[1]); // // // Sorry for the length of this message, looking forward to hearing from you soon // // // Vincent Morand // // // // //

My suggestion is to change in the implementation of cumulativeProbability(double) to catch all ConvergenceException (and return for very large and very small values), not just MaxIterationsExceededException. ``` You are a professional Java test case writer, please create a test case named `testExtremeValues` for the issue `Math-MATH-414`, utilizing the provided issue report information and the following function signature. ```java public void testExtremeValues() throws Exception { ```

```markdown ## Issue-ID: Gson-1053 ## Issue-Title: Negative zero ## Issue-Description: Hi, I have been cross testing various json parsers looking for those that expose the lexical of json numbers and not only their bound java.lang.Number. Because of the lazy parsing done by gson with `LazilyParsedNumber`, that keeps the lexical, all my roundtrip tests pass apart one: the lexical `-0` that is treated as it were `0` I read some threads about negative zero: <https://www.ietf.org/mail-archive/web/json/current/msg03668.html> <https://www.ietf.org/mail-archive/web/json/current/msg01520.html> <https://www.ietf.org/mail-archive/web/json/current/msg01523.html> <https://www.ietf.org/mail-archive/web/json/current/msg01525.html> I created this issue thinking that `-0` is a float, the same as `-0.0`, since a signed zero makes sense only in floating point numbers and also because in Java only Double/Float preserve sign of zero. This would have the implication that `-0` could not be validated by jsonschema `type` `integer` , and that a jsonschema implementation would have the need to know if a `-0` is present in json data, but probably this is not the case. After I started to (re)consider that `-0` could be an integer, only that seems that in no programming language there is an integer that preserves sign for zero. In any case, differentiating between `0` and `-0` at lexical level would allow a client of gson to be able to refuse the value `-0`. Gson could easily support differentiating between `0` and `-0`: in code `-0` is [treated as an integer (PEEKED\_LONG) in JsonReader](https://github.com/google/gson/blob/master/gson/src/main/java/com/google/gson/stream/JsonReader.java#L731) so its value is stored in a Java `long` that cannot represent negative zero. I noted that `-0.0` roundtrips correctly because is treated as a PEEKED\_NUMBER that is kept as a Java String. So the case of `-0` could be trapped and treated as `-0.0`, as a PEEKED\_NUMBER, in this way the `toString()` method of `LazilyParsedNumber` will return `-0` and gson will be able to roundtrip any valid number value found in source, only clients using `Number.toString()` will notice any difference. My proposal is to change [this code](https://github.com/google/gson/blob/master/gson/src/main/java/com/google/gson/stream/JsonReader.java#L731) from ``` if (last == NUMBER_CHAR_DIGIT && fitsInLong && (value != Long.MIN_VALUE || negative)) { ``` to ``` if (last == NUMBER_CHAR_DIGIT && fitsInLong && (value!=0 || false==negative) && (value != Long.MIN_VALUE || negative)) { ``` Thanks, Michele ``` You are a professional Java test case writer, please create a test case named `testNegativeZero` for the issue `Gson-1053`, utilizing the provided issue report information and the following function signature. ```java public void testNegativeZero() throws Exception { ```

```markdown ## Issue-ID: Compress-COMPRESS-314 ## Issue-Title: TarArchiveInputStream rejects uid or gid >= 0x80000000 ## Issue-Description: A POSIX-format archive that came from sysdiagnose produces NumberFormatException[1] when I try to read it with TarArchiveInputStream. The relevant part of the .tar file looks like this: 18 uid=429496729 That's the uid of 'nobody' on Mac OS (on Mac OS, uid\_t is 'unsigned int'). POSIX doesn't say anything about the width of the uid extended header[2], so I assume the tar file is okay. GNU tar doesn't have trouble with it. The relevant code, in applyPaxHeadersToCurrentEntry: } else if ("gid".equals(key)) { currEntry.setGroupId(Integer.parseInt(val)); ... } else if ("uid".equals(key)){ currEntry.setUserId(Integer.parseInt(val)); uid\_t and gid\_t are typically unsigned 32-bit integers, so these should presumably use Long.parseLong to handle integers with the top bit set (and TarArchiveEntry would need some modifications to handle large uid and gid, too).

```markdown ## Issue-ID: Math-MATH-938 ## Issue-Title: Line.revert() is imprecise ## Issue-Description: Line.revert() only maintains ~10 digits for the direction. This becomes an issue when the line's position is evaluated far from the origin. A simple fix would be to use Vector3D.negate() for the direction. Also, is there a reason why Line is not immutable? It is just comprised of two vectors. ``` You are a professional Java test case writer, please create a test case named `testRevert` for the issue `Math-MATH-938`, utilizing the provided issue report information and the following function signature. ```java @Test public void testRevert() { ```

// You are a professional Java test case writer, please create a test case named `testNonFiniteDoublesWhenLenient` for the issue `Gson-1090`, utilizing the provided issue report information and the following function signature. // ## Issue-ID: Gson-1090 // // ## Issue-Title: // JsonWriter#value(java.lang.Number) can be lenient, but JsonWriter#value(double) can't, // // ## Issue-Description: // In lenient mode, JsonWriter#value(java.lang.Number) can write pseudo-numeric values like `NaN`, `Infinity`, `-Infinity`: // // // // ``` // if (!lenient // && (string.equals("-Infinity") || string.equals("Infinity") || string.equals("NaN"))) { // throw new IllegalArgumentException("Numeric values must be finite, but was " + value); // } // ``` // // But JsonWriter#value(double) behaves in different way: // // // // ``` // if (Double.isNaN(value) || Double.isInfinite(value)) { // throw new IllegalArgumentException("Numeric values must be finite, but was " + value); // } // ``` // // So, while working with streaming, it's impossible to write semi-numeric value without boxing a double (e. g. `out.value((Number) Double.valueOf(Double.NaN))`). // // // I think, this should be possible, because boxing gives worse performance. // // // //

These formulas fail when vectors are almost colinear, like in the following example: // // // // // ``` // Vector3D v1 = new Vector3D(9070467121.0, 4535233560.0, 1); // Vector3D v2 = new Vector3D(9070467123.0, 4535233561.0, 1); // System.out.println(Vector3D.crossProduct(v1, v2)); // // ``` // // // The previous code displays // // // { -1, 2, 0 } // instead of the correct answer // // // { -1, 2, 1 } // // //

```markdown ## Issue-ID: Mockito-92 ## Issue-Title: Allow convenient spying on abstract classes ## Issue-Description: I posted this in GoogleCode and was asked to submit in github. Mockito is easy to use when the test needs to provide canned values for a certain method. But it gets harder when a canned value isn't sufficient. ##### Example 1: Fake with trivial Logic ``` interface UserAccount { List<String> getEmails(); void addEmail(String email); // 12 other methods ... } ``` When mocking such domain entity object, it's tedious to manually program getEmails()/addEmail() with when().thenReturn() and to make sure the two methods are logically consistent, that is, getEmails() returns all emails added. ##### Example 2: callback-style API ``` interface AccountService { void getAccount(String id, AsyncCallback<UserAccount> callback); } ``` Stubbing AccountService isn't easy. It'd require use of Answer, and the Answer API isn't statically type safe: ``` when(service.getAccount(eq(id), any(AsyncCallback.class)).thenAnswer(new Answer<Void>() { AsyncCallback<UserAccount> callback = (AsyncCallback<UserAccount>) getArguments()[1]; ... }); ``` ##### Example 3: Uninteresting parameters ``` interface AccountRpcService { FutureAccount getAccount(RpcContext context, String id); } ``` None of the tests care about the context object. It's an uninteresting parameter imposed by the framework. If AccountRpcService were directly mocked, all tests would have to use isA() to repetitively mention this uninteresting parameter, like this: `when(service.getAccount(isA(RpcContext.class), eq("id")).thenReturn(...);` And all other parameters are required to be wrapped in eq(). #### Proposal I propose adding support for abstract classes to mockito to make it easier to deal with tests like above: ##### For example 1 ``` abstract class FakeUserAccount implements UserAccount { private final List<String> emails = new ArrayList<>(); @Override public void addEmail(String email) { emails.add(email); } @Override List<String> getEmails() { return ImmutableList.copyOf(emails); } } @Fake private FakeUserAccount userAccount; // Mockito instantiates abstract class. ``` ##### For example 2 ``` abstract class MockAccountService implements AccountService { @Override public void getAccount(String id, AsyncCallback<UserAccount> callback) { callback.onSuccess(getAccount(id)); } abstract UserAccount getAccount(String id); } @Fake private MockAccountService service; ... when(service.getAccount("id")).thenReturn(account); ``` ##### For example 3 ``` abstract class MockAccountRpcService implements AccountRpcService { @Override Future<Account> getAccount(RpcContext context, String id) { checkNotNull(context); // Common sanity test. Don't have to repeat it in tests. return getAccount(id); } abstract Future<Account> getAccount(String id); } @Fake private MockAccountRpcService service; when(service.getAccount("id")).thenReturn(...); ``` My work place internally implemented a default Answer to support abstract classes. We found that the support of abstract classes helps us to avoid overusing mocks when we should be using fakes. And in situations like above we get cleaner test code. But because it's not integrated in the core Mockito, there are gotchas with our implementation (like, you can't have private/final methods in your fake). If the idea sounds okay to give a try, I'll volunteer to submit a patch. Thanks! ``` You are a professional Java test case writer, please create a test case named `should_spy_inner_class` for the issue `Mockito-92`, utilizing the provided issue report information and the following function signature. ```java @Test public void should_spy_inner_class() throws Exception { ```

// You are a professional Java test case writer, please create a test case named `should_spy_inner_class` for the issue `Mockito-92`, utilizing the provided issue report information and the following function signature. // ## Issue-ID: Mockito-92 // // ## Issue-Title: // Allow convenient spying on abstract classes // // ## Issue-Description: // I posted this in GoogleCode and was asked to submit in github. // // // Mockito is easy to use when the test needs to provide canned values for a certain method. // // // But it gets harder when a canned value isn't sufficient. // // // ##### Example 1: Fake with trivial Logic // // // // ``` // interface UserAccount { // List<String> getEmails(); // void addEmail(String email); // // 12 other methods ... // } // // ``` // // When mocking such domain entity object, it's tedious to manually program getEmails()/addEmail() with when().thenReturn() and to make sure the two methods are logically consistent, that is, getEmails() returns all emails added. // // // ##### Example 2: callback-style API // // // // ``` // interface AccountService { // void getAccount(String id, AsyncCallback<UserAccount> callback); // } // // ``` // // Stubbing AccountService isn't easy.
