-   Compiling capstone by hand will require setting [CMakeLists.txt](CMakeLists.txt#L109) accordingly

 # Limitations: #
+
+
 * Only Linux is supported
 * Only x86\_64 and RISC-V are supported
 * Only tested with glibc, although perhaps it works
 with some other libc implementations as well
 * RISC-V version assumes `$t6` is not used as base pointer or as source
 register without being reinitialized after an `ecall` and before the ending of
-a function - tested with glibc 2.35, 2.37 and 2.39
-* :warning: **Clone** is not fully handled on **RISC-V**. Whereas in x86_64
-   version it is possible to define post-clone hook functions for both the
-   parent and child threads, on RISC-V it is only possible to define a pre-clone
-   hook function therefore providing a similar interception to every other system
-   calls. An example is present in [intercept_sys_clone.c](test/riscv/src/intercept_sys_clone.c)
+a function. While this assumption involves heuristics, this choice was tested 
+on different glibc version, i.e. 2.35, 2.37 and 2.39, and on different kernel
+implementations manifesting a consistent and working behaviour.
 
 # Debugging: #
+
 Besides logging, the most important factor during debugging is to make
 sure the system calls in the debugger are not intercepted. To achieve this, use
 the INTERCEPT_HOOK_CMDLINE_FILTER variable described above.

+# Test directory #
+
+All the source files for executables and initialization libraries and utility
+files for testing are stored here. In the current directory only architecture
+agnostic tests are present, while architecture specific tests are stored in a
+dedicated directory inside `arch/`. As an example, inside `arch/x86_64/` some
+assembly tests are stored, which must be optionally compiled just when building
+on amd64 CPUs.
+
+
+**RISC-V specific tests are coming soon**. However, the architecture agnostic
+test suite can be run properly.
+
+# How to build #
+
+Tests are automatically built when building the library. If the library still
+has to be built, from the root directory of the project run
+```shell
+mkdir build
+cd build
+cmake ..
+make
+```
+
+[CMakeLists.txt](CMakeLists.txt) is written to automatically detect the CPU
+architecture and select which tests must be compiled accordingly.
+
+In the end, running
+```shell
+make test
+```
+will run the compiled test suite.
+
+# Testing logic #
+
+Different approaches are used to test syscall_intercept but an overall
+distinction can be made between high-level and low-level coded tests.
+- **Matching tests**: these tests verify the correct execution of the system 
+    call interception. Some of them use the library logging logic to produce a 
+    log file which gets then inspected to make sure it matches the expected output.
+    I.e., [syscall_format.c](syscall_format.c) makes a lot of system calls of
+    in a mock context just to create a log file which will be compared to
+    [syscall_format.log.match](syscall_format.log.match). One mismatch is enough
+    to fail the test.<br>Since system calls implementation may vary across
+    different glibc versions, the .match files could need to be updated to grant
+    a correct testing process. Depending on the glibc versions an `fstat` system
+    call could actually call `fstat` or `newfstatat`, or a `fstat` call with a
+    negative file descriptor could be forwarded to the kernel (invoking
+    syscall_intercept logic) or return before invoking the kernel (not invoking
+    syscall_intercept logic at all, and so the logging). Current .match files are
+    designed with glibc 2.35 and 2.39 versions in mind, which are the default
+    shipped versions with Ubuntu 22.04 and 24.04 respectively. Moreover, even the
+    same version on different architectures could involve different implementations.
+    <br>For these reasons, failing of a test of such type does not necessarily
+    imply that syscall_intercept is malfunctioning.
+- **Assertion tests**: these tests basically assert a condition which can't possibly be true unless
+  the hook function is executed as expected thanks to a correct interception of
+  the tested system call. As an example, the `write` test writes a string to a
+  file, then reads the written string from that file and in the end asserts that
+  the two strings are perfectly equal. By looking at the content of
+  [write_test.c](src/write_test.c) it is obvious how the assertion could never be
+  true since the written string and the expected string are different. The hook
+  function which will be executed before forwarding the system call to the kernel
+  will make sure to modify the string that is going to be written to the file so
+  that the actual written string and the expected string match.
+  All the tests implementing such pattern are named in the suite as `<syscall-name>_generic`.
+- **Patching tests**: these tests verify the correct execution of the patching 
+  process. They work in couples with an input and an output pattern file, both
+  coded in assembly. The input object file will be patched by syscall_intercept
+  producing a patched binary which will be compared with the output file by
+  `memcmp()`. Failing of such tests implies that the patching process is not
+  writing the expected binary code.<br>**RISC-V tests of such type are coming soon.**
+
+Assertion tests must be considered as couples containing an executable
+and an initialization library, named as follows:
+- `<syscall-name>_test.c`
+- `intercept_sys_<syscall-name>.c`
+
+Granted that syscall_intercept is already built, assertion tests can alternatively
+be compiled in this directory with
+```shell
+make
+```
+and executed with
+```shell
+make test
+```
+
+Alternatively, it is possible to execute a specific test with the following
+command, where syscall-name must be replaced with one of the entries in
+the TESTS variable in the Makefile
+```
+make <syscall-name>
+```

-# Testing on RISC-V #
-
-The tests inside `./src` must be considered as couples containing an executable
-and an initialization library, named as follows:
-- `<syscall-name>_test.c`
-- `intercept_sys_<syscall-name>.c`
-
-They can be compiled with
-```shell
-make
-```
-and executed with
-```shell
-make test
-```
-Alternatively, it is possible to execute a specific test with the following
-command, where syscall-name must be replaced with one of the entries in
-the TESTS variable in the Makefile
-```
-make <syscall-name>
-```
-
-## How these test work ##
-
-These tests basically assert a condition which can't possibly be true unless
-the hook function is executed as expected thanks to a correct interception of
-the tested system call. As an example, the `write` test writes a string to a
-file, then reads the written string from that file and in the end asserts that
-the two strings are perfectly equal. By looking at the content of
-[write_test.c](src/write_test.c) it is obvious how the assertion could never be
-true since the written string and the expected string are different. The hook
-function which will be executed before forwarding the system call to the kernel
-will make sure to modify the string that is going to be written to the file so
-that the actual written string and the expected string match.
-All the tests implement the described pattern.
