are structured along the features of the library or the nature of the tests. Usually, it should be clear from the
|
||||
context which existing file needs to be extended, and only very few cases require creating new test files.
|
||||
|
||||
When fixing a bug, edit `unit-regression3.cpp` and add a section referencing the fixed issue. Tests that need C++17 or
|
||||
C++20 go into `unit-regression3-cpp17.cpp` or `unit-regression3-cpp20.cpp` instead, so the large file is not rebuilt
|
||||
for every C++ standard. `unit-regression2.cpp` holds the older tests; the two files exist because a single one grew
|
||||
large enough for the MinGW linker to fail relocating it, so please keep adding to the smaller file rather than growing
|
||||
the larger one.
|
||||
|
||||
To keep compile times down, several test files are compiled together as one translation unit. This sets a few rules
|
||||
for test files, such as giving file-scope helpers file-specific names. See the README in the
|
||||
[`tests`](https://github.com/nlohmann/json/tree/develop/tests) folder for how the tests are built and what to keep in
|
||||
mind when adding them.

### `JSON_TestUnityBuild`
|
||||
|
||||
Build the unit tests in batches of several test files per executable to speed up compilation: the files of a batch are
|
||||
compiled as one translation unit, so the template instantiations of the library are shared. Every test file still gets
|
||||
its own CTest test (e.g., `test-foo_cpp11`), which runs only the test cases of that file from the shared executable.
|
||||
This option is `ON` by default (and `OFF` with MinGW). Set it to `OFF` to get one executable per test file, e.g., when
|
||||
debugging a single file. The number of files per executable is set by the cache variable `JSON_TestUnityBatchSize`
|
||||
(default: `8`). Related test files (e.g., all binary formats) are grouped explicitly in `tests/CMakeLists.txt`; each
|

group is compiled as one executable per C++ standard regardless of the batch size, and only the remaining files are

# Unit tests
|
||||
|
||||
The unit tests are in [`src/unit-*.cpp`](src) and use [doctest](https://github.com/doctest/doctest). Each file becomes
|
||||
one CTest test per C++ standard it is built for, named after the file: `src/unit-foo.cpp` becomes `test-foo_cpp11`.
|
||||
|
||||
## Build and run
|
||||
|
||||
```sh
|
||||
cmake -S . -B build -DJSON_BuildTests=ON
|
||||
cmake --build build -j 10
|
||||
ctest --test-dir build -j 10
|
||||
```
|
||||
|
||||
The [CMake options](../docs/mkdocs/docs/integration/cmake.md) starting with `JSON_Test` (and `JSON_FastTests`,
|
||||
`JSON_Valgrind`) control the test build. The most relevant ones:
|
||||
|
||||
- `JSON_TestStandards`: build every test file for the given standards, e.g., `-DJSON_TestStandards=17`. By default,
|
||||
a file is built for C++11 and for each standard whose `JSON_HAS_CPP_<N>` macro it mentions (see below).
|
||||
- `JSON_TestUnityBuild`: compile several test files together (see below). Set it to `OFF` to get one executable per
|
||||
test file, e.g., to debug a single test in a debugger.
|
||||
- `JSON_TestShard`: build only a part of the test files, e.g., `-DJSON_TestShard=0/2`.
|
||||
|
||||
To run the tests of one file only, run its CTest test, e.g., `ctest --test-dir build -R test-foo_cpp11`.
|
||||
|
||||
## How test files are built
|
||||
|
||||
Two mechanisms keep the compile time down. Both are automatic, but they set a few rules for test files.
|
||||
|
||||
### C++ standards
|
||||
|
||||
A test file is built for a C++ standard beyond C++11 if its text contains `JSON_HAS_CPP_<N>`, for instance in
|
||||
`#ifdef JSON_HAS_CPP_17`, or in a comment `// JSON_HAS_CPP_17` next to code that needs a macro only defined for that
|
||||
standard, such as `JSON_HAS_FILESYSTEM`. Then the *whole file* is compiled again for that standard.
|
||||
|
||||
So that this does not happen for the large files, tests that need C++14, C++17, or C++20 go into a separate file
|
||||
`src/unit-<name>-cpp<N>.cpp` (e.g., [`src/unit-regression3-cpp17.cpp`](src/unit-regression3-cpp17.cpp)), whose body
|
||||
is wrapped in `#ifdef JSON_HAS_CPP_<N>`. The main file `src/unit-<name>.cpp` must not mention `JSON_HAS_CPP_<N>` at
|
||||
all, not even in a comment, so it is built for C++11 only. The CI jobs `ci_test_*_cxx<N>` still build every test file
|
||||
for every standard.
|
||||
|
||||
### Unity build
|
||||
|
||||
With `JSON_TestUnityBuild` (`ON` by default, `OFF` with MinGW), CMake compiles several test files as one translation
|
||||
unit, so they share the template instantiations of the library. CMake generates `build/tests/unity/test-unity-*.cpp`,
|
||||
which `#include` the test files of a batch. Every test file still gets its own CTest test, which runs the batch
|
||||
executable with `--source-file=*unit-foo.cpp`, so only the test cases of that file run.
|
||||
|
||||
CMake decides from the macros a file defines *before* including `<nlohmann/json.hpp>`:
|
||||
|
||||
| Macros defined before the include | Built as |
|
||||
|-------------------------------------------------------------------------------------------|-----------------------------------|
|
||||
| none (or only `SKIP_TESTS_FOR_*` and similar macros derived from global definitions) | batch with the other plain files |
|
||||
| only `JSON_TESTS_PRIVATE` | batch with the other such files |
|
||||
| any library configuration macro (`JSON_DIAGNOSTICS`, `JSON_NO_IO`, `JSON_ASSERT`, ...) | its own executable |
|
||||
|
||||
Files with test-specific build options (`json_test_set_test_options(test-foo ...)` in
|
||||
[`CMakeLists.txt`](CMakeLists.txt)) also get their own executable. The batchable files are split alphabetically into
|
||||
batches of `JSON_TestUnityBatchSize` files, except for explicit groups of related files: `json_test_unity_group_binary`
|
||||
compiles all binary-format tests together, because they share the binary readers and writers. Only add a group if it
|
||||
measurably pays off; files that share little just make one slow translation unit.
|
||||
|
||||
## Rules for test files
|
||||
|
||||
Because the files of a batch share one translation unit, a test file must not affect the files that follow it:
|
||||
|
||||
1. **Give file-scope helpers file-specific names.** An anonymous namespace does not help, as the batch is one
|
||||
translation unit. Use a name such as `my_allocator_2982`, or wrap the helpers in a namespace named after the file
|
||||
(e.g., `namespace unit_comparison_detail`). Clashes show up as compile errors.
|
||||
2. **Do not `#undef` library macros**, such as `JSON_HAS_CPP_17`, at the end of a file: this silently disables the tests
|
||||
that depend on them in the later files of the batch. `#undef` macros you define yourself after including the library.
|
||||
3. **Put version-dependent tests into `unit-<name>-cpp<N>.cpp`** (see [C++ standards](#c-standards)).
|
||||
4. **Define test cases in the `.cpp` file itself.** The batch executable selects the tests of a file by its name, so a
|
||||
`TEST_CASE` in a shared header is not run. The only exception is the test case in
|
||||
[`src/make_test_data_available.hpp`](src/make_test_data_available.hpp), which CMake handles explicitly.
|
||||
|
||||
To check a new file for clashes with all others at once, build with `-DJSON_TestUnityBatchSize=1000`, which puts all
|
||||
batchable files of a kind into one translation unit.
|
||||
|
||||
## Where to add tests
|
||||
|
||||
Tests are structured along the features of the library. Usually, an existing file is the right place:
|
||||
|
||||
- For a bug fix, add a section referencing the issue to [`src/unit-regression3.cpp`](src/unit-regression3.cpp), or to
|
||||
[`src/unit-regression3-cpp17.cpp`](src/unit-regression3-cpp17.cpp) /
|
||||
[`src/unit-regression3-cpp20.cpp`](src/unit-regression3-cpp20.cpp) if the test needs C++17 / C++20.
|
||||
[`src/unit-regression2.cpp`](src/unit-regression2.cpp) holds older tests and should not grow further.
|
||||
- When testing exceptions, use `CHECK_THROWS_WITH_AS`, which also checks the `what()` message.
|
||||
|
||||
A new file `src/unit-<name>.cpp` is picked up automatically when CMake runs again; no change to `CMakeLists.txt` is
|
||||
needed.
|
||||
|
||||
See also [`fuzzing.md`](fuzzing.md) for fuzz testing.
