+# How to run specific section/generator
+
+> The generator and generic path filtering was added in Catch2 3.13.0
+
+Catch2 supports picking specific path through a test case by filtering
+sections and generator indices to run through. This is done by using one
+of the three commandline parameters, one or more times.
+
+```
+-c, --section           <section name>
+-g, --generator-index   <index in generator>
+-p, --path-filter       <path filter spec>
+```
+
+All the variants form a shared stack of filters, but if you use only
+`-c`/`--section` form to specify section filters, you will get the old
+behaviour, which does not affect generators at all. If you also use either
+`-g`/`--generator-index`, or `-p`/`--path-filter`, you will get the new
+behaviour, which can also filter generator elements.
+
+Both the new and old filter behaviours include some potentially surprising
+things:
+  * Code outside of sections being skipped will still be executed. E.g.
+    any setup code in the TEST_CASE that lives outside of sections.
+  * Path filters filter the prefix of the path. So if you specify single
+    filter, it affects only the top level sections/generator, with their
+    child sections/generators being unfiltered.
+  * Path filters are independent of test case selection, Catch2 will try
+    to follow the path filters in all selected test cases. This means
+    that if you specify path filters without a test case filter, Catch2
+    will try to apply the path filters inside every registered test case.
+
+## Old behaviour
+
+> The old behaviour was deprecated in Catch2 3.13.0
+
+```
+-c, --section           <section name>
+```
+The argument to `-c`/`--section` can be any arbitrary string. When Catch2
+is deciding whether to enter a section, it will check its trimmed name
+against the appropriate trimmed section filter. If they are the same,
+the section can be opened. If not, Catch2 will skip over that section.
+
+
+### Examples
+
+#### Simple section nesting
+Given
+```cpp
+TEST_CASE( "foo" ) {
+    REQUIRE( true );
+    SECTION( "A" ) {
+        SECTION( "A1" ) { REQUIRE( true ); }
+        SECTION( "A2" ) { REQUIRE( true ); }
+    }
+    SECTION( "B" ) {
+        SECTION( "B1" ) { REQUIRE( true ); }
+        SECTION( "B2" ) { REQUIRE( true ); }
+    }
+}
+```
+
+* `./tests foo -c A` runs section "A" and both of its subsections,
+   resulting in 4 assertions.
+* `./tests foo -c A -c B` runs section "A", but none of its subsections,
+   resulting in 1 assertion (the one before "A").
+* `./tests foo -c A -c A1` runs section "A" and only the "A1" subsection,
+   resulting in 2 assertions.
+
+
+#### Sections with nested generators
+Note that old behaviour completely _ignores_ generators. This means both
+that they can't be filtered, but also that they aren't taken into account
+for the filter depth. In other words, given
+```cpp
+TEST_CASE( "bar" ) {
+    REQUIRE( true );
+    SECTION( "A" ) { REQUIRE( true ); }
+    SECTION( "B" ) {
+        auto i = GENERATE( 1, 2, 3 );
+        DYNAMIC_SECTION( "i=" << i ) {
+            REQUIRE( true );
+        }
+    }
+}
+```
+* `./tests bar -c A` results in 2 assertions.
+* `./tests bar -c B -c i=2` results in 4 assertions, because the whole
+  generator in section "B" has to be used up, but the dynamic section is
+  only entered when the generator returns 2 as the value for `i`.
+* `./tests bar -c B -c i=4` results in 3 assertions, because the assertion
+  outside of section is executed every time the test case is entered, and
+  the generator forces the test case to rerun 3 times before it is used up,
+  even though the dynamic section will never be entered.
+
+
+#### Section with sibling generators
+For cases where sections have sibling generators, the filtering can get
+even more surprising.
+```cpp
+TEST_CASE( "qux" ) {
+    REQUIRE( true );
+    SECTION( "A" ) { REQUIRE( true ); }
+    auto i = GENERATE( 1, 2, 3 );
+    DYNAMIC_SECTION( "i=" << i ) {
+        REQUIRE( true );
+    }
+}
+```
+* `./tests qux -c A` results in **4** assertions, because section "A" is
+  entered once, but the sibling generator has to be exhausted, and
+  the first assertion is executed once per generator element.
+* `./tests qux -c i=2` also results in 4 assertions. Once again,
+  the generator has to be exhausted and the dynamic section is entered
+  once.
+
+
+## New behaviour
+
+> The new behaviour was introduced in Catch2 3.13.0
+
+```
+-g, --generator-index   <index in generator>
+-p, --path-filter       <path filter spec>
+```
+
+The argument to `-g`/`--generator-index` must be either a non-negative
+number, which is interpreted as the index of the desired element from
+the generator, or "\*", which allows all elements from the generator.
+
+Providing index outside of the generator is an error.
+
+The argument to `-p`/`--path-filter` must start with either "c:" for
+a section filter, or with "g:" for a generator filter. Everything past
+the colon is then parsed as either a section filter, or a generator filter.
+
+Note that using `p`/`--path-filter` enables new filtering behaviour, even
+if it is only used to add section filters.
+
+There is another important difference between filtering out sections and
+generators. A section can be left un-entered, but a generator always has
+to be active. For this reason, if generator fails a filter
+(e.g. there is a section filter at given depth instead), it has to stop
+the execution of the test case. Currently, this is done via `SKIP()`
+equivalent, causing the section to be considered skipped.
+
+
+### Examples
+
+#### Nested generators
+```cpp
+TEST_CASE( "waldo" ) {
+    auto i = GENERATE( 1, 10, 100 );
+    auto j = GENERATE( 2, 20, 200 );
+    CAPTURE( i, j );
+    REQUIRE( true );
+}
+```
+* `./tests waldo -g 1` results in 3 assertions, with `i := 10`, because
+  the second nested generator is unfiltered.
+* `./tests waldo -g 1 -g 2` results in 1 assertion, with `i := 10, j := 200`.
+* `./tests waldo -g * -g 2` results in 3 assertions, all with `j := 200`.
+* `./tests waldo -g 1 -g *` results in 3 assertions, all with `i := 10`.
+* `./tests waldo -g 3` results in 1 **failed** assertion, because the first
+  generator does not have 3rd element.
+* `./tests waldo -g * -g 3` results in 3 **failed** assertions, as the
+  second generator does not have 3rd element, but we have to exhaust the
+  first generator.
+
+#### Generator with a nested dynamic section
+```cpp
+TEST_CASE( "grault" ) {
+    REQUIRE( true );
+    auto i = GENERATE( 1, 2, 3 );
+    DYNAMIC_SECTION( "i=" << i ) {
+        REQUIRE( true );
+    }
+}
+```
+* `./tests grault -p g:1` results in 2 assertions, as there is no filter
+  on the dynamic section.
+* `./tests grault -p g:1 -p c:i=2` results in 2 assertions, as the filter
+  on the dynamic section matches the element given from the generator.
+* `./tests grault -p g:1 -p c:i=3` results in 1 assertion, as the generator
+  is limited to only try `i := 2` and the dynamic section is filtered out.
+
+#### Section with a sibling generator
+Because generators have to stop test execution when they don't pass filter,
+it is impossible to run only a section with sibling generator without
+triggering a test case skip. Consider this test case from an earlier example:
+```cpp
+TEST_CASE( "qux" ) {
+    REQUIRE( true );
+    SECTION( "A" ) { REQUIRE( true ); }
+    auto i = GENERATE( 1, 2, 3 );
+    DYNAMIC_SECTION( "i=" << i ) {
+        REQUIRE( true );
+    }
+}
+```
+* `./tests qux -p g:1` results in 2 assertions, as the dynamic section is
+  entered only once.
+* `./tests qux -p g:1 -p c:i=1` results in 1 assertion, as the dynamic
+  section filter is incompatible with the generator filter.
+* `./tests qux -p c:A` results in 2 assertions **and a skipped test case**.
+  This is because the generator is sibling to section "A", and thus reads
+  the same section filter. However, it is not a section and as thus cannot
+  proceed.
+* `./tests qux -p c:i=2` results in 1 assertion **and a skipped test case**.
+  Once again, the first filter in the filter stack is a section filter,
+  and thus the generator cannot proceed.
+
+Compare this with the old filter behaviour, where `./tests qux -c i=2`
+would instead result in 4 assertions, because the generator would go
+through all elements.

+## Other usage examples
+
+### Adding a reproducer to random tests
+
+If you use generators to generate random inputs for testing, you might
+want to combine them with specific inputs, e.g. reproducers for previously
+found issues.
+
+Because `GENERATE` accepts multiple values/generators, the basic case is simple:
+```cpp
+const int input = GENERATE(1, 2, take(10, random(10, 10'000'000)));
+```
+This will set `input` first to "1", then to "2", and then to 10 random
+integers.
+
+But if you process the random inputs further (e.g. via `map`), you can't
+rely on `GENERATE`'s support for multiple generators. In that case, you
+have to use the `cat` generator combinator.
+```cpp
+const auto input = GENERATE(
+    map( foo,
+         cat( value( 4 ), take( 10, random( 10, 10'000'000 ) ) ) ) );
+```
+This will set `input` first to `foo(4)`, before transforming the 10 random
+integers through `foo`.

Sung, Po Han	f4e83daa18	Fix catch_discover_tests PRE_TEST failure with zero discoverable tests When using catch_discover_tests() with DISCOVERY_MODE PRE_TEST and a multi-config generator (e.g. Ninja Multi-Config), if a test target has zero discoverable tests (e.g. all tests tagged with [.]), ctest fails: CMake Error: include could not find requested file: .../test-hidden-b12d07c_tests-Release.cmake The early return added in #2962 (`76f70b14`) correctly prevented a JSON parsing crash for zero tests, but skipped writing the ctest file. The PRE_TEST include script unconditionally includes this file, so the missing file causes a hard error that aborts all test discovery. Write an empty file before returning early so the include always succeeds.	2026-04-02 10:24:46 +02:00

Martin Hořeňovský	51b0532d1f	Suppress __COUNTER__ warning from newest Clang versions Ideally we could suppress the warning locally in the `UNIQUE_NAME` macro, but that runs into at least 2 issues: 1) Clang actually does not consider the warning as coming from inside the `UNIQUE_NAME` macro, even though it correctly points to its expansion as the problem. This means that adding `_Pragma`s inside the macro around the __COUNTER__ usage does not actually silence the warning. 2) Adding the local suppressions anyway breaks the expansion of `MAKE_NAMESPACE` macro inside the templated test case macros. This can be fixed for the newest clang version by removing its use and using the uniqued `TestName` for the namespace name directly, but this breaks compilation on GCC, and older Clang versions. Because of these issues, we introduce global warning suppression for `-Wc2y-extensions` to be done with it. We should revisit this if Clang 23 fixes the local pragma based suppression, when it might be worth the effort to rework the templated test case macros to support it.

Martin Hořeňovský	056e4fe88d	MapGenerator only calls mapping function if the result is used Previously the mapping was eager on construction and calls to `next()`. This was fine when generators were always exhausted fully, but with the new generator filtering, we might not want to call the map function eagerly; rather we want to call it only once, after the generator is moved to the target element.	2026-02-15 20:44:21 +01:00
Martin Hořeňovský	3a0cf7e75f	Support filtering on both sections and generators (#3069 ) Not being able to filter generators to specific element has been regularly causing problems. It was possible to use a dynamic section to run tests for specific element in a generator, at least if the element had a nice string representation, but the test case would still run once per element in the generator. With this change, it is possible to have the generator return only one specific element, and do so based on the index, rather than the string representation of the element. This enables simple debugging of tests that fail for specific generator element.	2026-02-15 20:27:15 +01:00

Martin Hořeňovský	eb3811c555	Fix lifetime issues when using UNSCOPED_X message macros The original implementation of `UNSCOPED_X` message macros used a clever hack to make the original implementation simpler: construct an instance of `ScopedMessage` to manage its lifetime, but store it in a vector, so its lifetime is not actually scope-based, and we can manage it through the vector instance. This hack made it so that the lifetime of the vector that manages the fake `ScopedMessage`s must be outlived by the vector with the actual messages. Originally this wasn't a problem, because they both lived inside the run context instance. However, since then these vectors became globals and thread-local. When this happened, it still wasn't a problem; the two globals were declared in the right order, so they were destroyed in the right order as well. Then, in `f80956a43a`, these globals were turned into magic static globals to improve their behaviour in MSVC's Debug build mode. This caused their lifetimes to be runtime-dependent; if a specific test thread added its first scoped message before it added first unscoped message, the lifetimes would be correct. If it instead added first unscoped message before adding first scoped message, then there might be invalid reads during thread destruction. The fix is simple: do things properly and manage the lifetime of messages in `UNSCOPED_X` explicitly. Then we don't have to deal with the destruction of fake `ScopedMessage`s while the thread is being destroyed, and the lifetime of the two vectors is no longer tied together. I also threw them both into a new type, to encapsulate some of the unscoped message logic.	2025-12-26 15:53:30 +01:00
Martin Hořeňovský	343cc059fe	Move to newer MacOS GHA runners Macos-13 runners were deprecated, and macos-15 family brings back intel runner that is usable by OSS projects.	2025-12-23 16:12:23 +01:00

Martin Hořeňovský	f80956a43a	Use magic statics for non-trivial thread-local globals This avoids calling the global's constructor on threads that will never interact with them. Calling the constructor can have surprising overhead, as e.g. MSVC's Debug mode `std::vector` will allocate in the default constructor. Closes #3050	2025-12-02 14:19:21 +01:00
Martin Hořeňovský	32eac2d1bb	Only use thread_local in builds with thread safety enabled MSVC cannot dllexport thread_local variables, so we avoid making globals thread local if we won't support multiple threads anyway. Closes #3044	2025-12-02 14:01:55 +01:00

Martin Hořeňovský	8e4ab5dd8f	Annotate matcher combinators with CATCH_ATTR_LIFETIMEBOUND The matcher combinators do not take ownership of the matchers being combined, which can catch the users off-guard, when code like this ```cpp using Catch::Matchers::EndsWith; using Catch::Matchers::ContainsSubstring; auto combinedMatcher = EndsWith("as a service") && ContainsSubstring("web scale"); REQUIRE_THAT( getSomeString(), combinedMatcher ); ``` leads to use-after-free, as the `combinedMatcher` refers to matcher temporaries that no longer exists. With this commit, users of Clang, MSVC or other compiler that understands the `lifetimebound` attribute, should get a warning.	2025-10-03 22:27:29 +02:00
