Icon Linkforc-test

Run the Sway unit tests for the current project.

NOTE: Previously this command was used to support Rust integration testing, however the provided behaviour served no benefit over running cargo test directly. The proposal to change the behaviour to support unit testing can be found at the following link: https://github.com/FuelLabs/sway/issues/1833

Sway unit tests are functions decorated with the #[test] attribute. Each test is compiled as a unique entry point for a single program and has access to the namespace of the module in which it is declared.

Unit tests decorated with the #[test(script)] attribute that are declared within contractprojects may also call directly into their associated contract's ABI.

Upon successful compilation, test scripts are executed to their completion. A test is considered a failure in the case that a revert (rvrt) instruction is encountered during execution. Otherwise, it is considered a success.

Icon LinkUSAGE:

forc test [OPTIONS] [FILTER]

Icon LinkARGS:

<FILTER> When specified, only tests containing the given string will be executed

Icon LinkOPTIONS:

--ast

Print the generated Sway AST (Abstract Syntax Tree)

--build-profile <BUILD_PROFILE>

Name of the build profile to use.

If unspecified, forc will use debug build profile.

--build-target <BUILD_TARGET>

Build target to use for code generation

[default: fuel] [possible values: fuel, evm, midenvm]

--dca-graph <DCA_GRAPH>

Print the computed Sway DCA graph. DCA graph is printed to the specified path. If specified '' graph is printed to stdout

--dca-graph-url-format <DCA_GRAPH_URL_FORMAT>

Specifies the url format to be used in the generated dot file. Variables {path}, {line} {col} can be used in the provided format. An example for vscode would be: "vscode://file/{path}:{line}:{col}"

--error-on-warnings

Treat warnings as errors

--filter-exact

When specified, only the test exactly matching the given string will be executed

--finalized-asm

Print the finalized ASM.

This is the state of the ASM with registers allocated and optimisations applied.

-g, --output-debug <DEBUG_FILE>

If set, outputs source file mapping in JSON format

-h, --help

Print help information

--intermediate-asm

Print the generated ASM.

This is the state of the ASM prior to performing register allocation and other ASM optimisations.

--ipfs-node <IPFS_NODE>

The IPFS Node to use for fetching IPFS sources.

Possible values: PUBLIC, LOCAL, <GATEWAY_URL>

--ir

Print the generated Sway IR (Intermediate Representation)

--json-abi

By default the JSON for ABIs is formatted for human readability. By using this option JSON output will be "minified", i.e. all on one line without whitespace

--json-abi-with-callpaths

Outputs json abi with callpaths instead of names for struct and enums

--json-storage-slots

By default the JSON for initial storage slots is formatted for human readability. By using this option JSON output will be "minified", i.e. all on one line without whitespace

-l, --logs

Print Log and LogData receipts for tests

-L, --log-level <LOG_LEVEL>

Set the log level

--locked

Requires that the Forc.lock file is up-to-date. If the lock file is missing, or it needs to be updated, Forc will exit with an error

--metrics-outfile <METRICS_OUTFILE>

Output compilation metrics into file

-o, --output-bin <BIN_FILE>

If set, outputs a binary file representing the script bytes

--offline

Offline mode, prevents Forc from using the network when managing dependencies. Meaning it will only try to use previously downloaded dependencies

--output-directory <OUTPUT_DIRECTORY>

The directory in which the sway compiler output artifacts are placed.

By default, this is <project-root>/out.

-p, --path <PATH>

Path to the project, if not specified, current working directory will be used

-r, --pretty-print

Pretty-print the logs emiited from tests

--release

Use release build plan. If a custom release plan is not specified, it is implicitly added to the manifest file.

If --build-profile is also provided, forc omits this flag and uses provided build-profile.

--reverse-order

Output build errors and warnings in reverse order

-s, --silent

Silence all output

-t, --terse

Terse mode. Limited warning and error output

--test-threads <TEST_THREADS>

Number of threads to utilize when running the tests. By default, this is the number of threads available in your system

--time-phases

Output the time elapsed over each part of the compilation process

-v, --verbose

Use verbose output
