Specifies a fuzzing engine that can be used to run Java fuzz targets.
ATTRIBUTES
Name | Description | Type | Mandatory | Default |
---|---|---|---|---|
name | A unique name for this target. | Name | required | |
display_name | The name of the fuzzing engine, as it should be rendered in human-readable output. | String | required | |
launcher | A shell script that knows how to launch the fuzzing executable based on configuration specified in the environment. | Label | required | |
launcher_data | A dict mapping additional runtime dependencies needed by the fuzzing engine to environment variables that will be available inside the launcher, holding the runtime path to the dependency. | Dictionary: Label -> String | optional | {} |
library | A java_library target that is made available to all Java fuzz tests. | Label | optional | None |
Provider for storing the language-independent part of the specification of a fuzzing engine.
FIELDS
Name | Description |
---|---|
display_name | A string representing the human-readable name of the fuzzing engine. |
launcher | A file representing the shell script that launches the fuzz target. |
launcher_runfiles | The runfiles needed by the launcher script on the fuzzing engine side, such as helper tools and their data dependencies. |
launcher_environment | A dictionary from environment variables to files used by the launcher script. |
Generates the standard targets associated to a fuzz test.
This macro can be used to define custom fuzz test rules in case the default cc_fuzz_test
macro is not adequate. Refer to the cc_fuzz_test
macro documentation for the set of targets generated.
PARAMETERS
Name | Description | Default Value |
---|---|---|
name | The name prefix of the generated targets. It is normally the fuzz test name in the BUILD file. | none |
raw_binary | The label of the cc_binary or cc_test of fuzz test executable. | none |
engine | The label of the fuzzing engine used to build the binary. | none |
corpus | A list of corpus files. | None |
dicts | A list of fuzzing dictionary files. | None |
instrument_binary | (Experimental, may be removed in the future.) By default, the generated targets depend on raw_binary through a Bazel configuration using flags from the @rules_fuzzing//fuzzing package to determine the fuzzing build mode, engine, and sanitizer instrumentation. When this argument is false, the targets assume that raw_binary is already built in the proper configuration and will not apply the transition. Most users should not need to change this argument. If you think the default instrumentation mode does not work for your use case, please file a Github issue to discuss. | True |
define_regression_test | If true, generate a regression test rule. | True |
test_tags | Tags set on the fuzzing regression test. | None |
Defines a Java fuzz test and a few associated tools and metadata.
For each fuzz test <name>
, this macro defines a number of targets. The most relevant ones are:
<name>
: A test that executes the fuzzer binary against the seed corpus (or on an empty input if no corpus is specified).<name>_bin
: The instrumented fuzz test executable. Use this target for debugging or for accessing the complete command line interface of the fuzzing engine. Most developers should only need to use this target rarely.<name>_run
: An executable target used to launch the fuzz test using a simpler, engine-agnostic command line interface.PARAMETERS
Name | Description | Default Value |
---|---|---|
name | A unique name for this target. Required. | none |
srcs | A list of source files of the target. | None |
target_class | The class that contains the static fuzzerTestOneInput method. Defaults to the same class main_class would. | None |
transitive_native_deps | A list of all native libraries that the fuzz target transitively depends on. The libraries are instrumented automatically and do not need to be mentioned in deps. Listing the libraries in this way is no longer required as of Bazel 5. | None |
corpus | A list containing corpus files. | None |
dicts | A list containing dictionaries. | None |
engine | A label pointing to the fuzzing engine to use. | “@rules_fuzzing//fuzzing:java_engine” |
tags | Tags set on the fuzzing regression test. | None |
binary_kwargs | Keyword arguments directly forwarded to the fuzz test binary rule. | none |
