@MohitMaliFtechiz This PR has to be based on #27, I don't understand how this can work otherwise.

@kelson42 , i have made this branch from #27 and after that added new test cases in it, Once #27 is merged i'll re base this PR on main branch.

currently test cases are failing of because Linux libzim tar file containing 0 bytes .so file, so i have open a ticket for it in libzim https://github.com/openzim/libzim/issues/772 .

[MohitMaliFtechiz]

For now i have made this branch from https://github.com/kiwix/java-libkiwix/pull/31 to avoid the build failure because of linux zim file.

@mgautierfr , I am getting some errors while adding new test cases, can you please help me out on these errors.

• When i am getting book from library Book book = lib.getBookById(bookIds[0]); via this method . It is giving error in utils.h

  /media/hp-pc03/D/java-libkiwix/lib/src/main/cpp/utils.h:71: void setPtr(JNIEnv*, jobject, std::shared_ptr<_Tp>&&, const char*) [with T = const kiwix::Book; JNIEnv = JNIEnv_; jobject = _jobject*]: Assertion `env->GetLongField(thisObj, fieldId) == 0' failed.

• When i am making object of query to test searcher Query query = new Query("test"); it is giving error. I think it means , it is not persent in .so file but we are including query.cpp while building the .so file. Is something missing in linux.so file or we are doing something wrong here?.

  java.lang.UnsatisfiedLinkError: 'long org.kiwix.libzim.Query.setNativeQuery(java.lang.String)'
  at org.kiwix.libzim.Query.setNativeQuery(Native Method)
  at org.kiwix.libzim.Query.<init>(Query.java:25)
  at test.testSearcher(test.java:216)

• When i am using suggestionSearch.getEstimatedMatches() it is returning 0 results. But i have tried small.zim with kiwix-app and search for test, there it is showing result in search result list .

  I have push all the latest test cases on this PR. Currently CI is not running, Can you please try to run these tests locally.

@mgautierfr any update?

@MohitMaliFtechiz First problem (setPtr) is fixed. But there is something wrong in the build system. I've spend a lot of time try to fix a crash in java interpreter and it was because the test was using a old version of the java .class definition (I think). I suppose that buildsystem doesn't detect correctly that .class have changed and don't update the one in the test directory.

I'm looking for the two others issues.

But on my side, I face a new test failure where the illustration data is not equal to expected (test.java:137). It is probably because the String constructor interpret the bytes (and probably stop at first \0).
