# Testing
|
||
|
||
There are two kinds of tests in Blockbook – unit tests and integration tests. Because integration tests require running
|
||
backend daemon so they can't be executed at every build. Blockbook's build system uses conditional compilation to
|
||
distinguish which tests should be executed.
|
||
|
||
To execute unit tests run `make test`. To execute unit tests and integration tests run `make test-all`. You can use
|
||
Go's flag *-run* to filter which tests should be executed. Use *ARGS* variable, e.g.
|
||
`make test-all ARGS="-run TestBitcoin"`.
|
||
|
||
## Unit tests
|
||
|
||
Unit test file must start with constraint `// +build unittest` followed by blank line (constraints are described
|
||
[here](https://golang.org/pkg/go/build/#hdr-Build_Constraints)).
|
||
|
||
Every coin implementation should have unit tests. At least for parser. Usual test suite define real transaction data
|
||
and try pack and unpack them. Specialites of particular coin are tested too. See examples in
|
||
[bcashparser_test.go](/bchain/coins/bch/bcashparser_test.go),
|
||
[bitcoinparser_test.go](/bchain/coins/btc/bitcoinparser_test.go) and
|
||
[ethparser_test.go](/bchain/coins/eth/ethparser_test.go).
|
||
|
||
|
||
## Integration tests
|
||
|
||
Integration test file must start with constraint `// +build integration` followed by blank line (constraints are
|
||
described [here](https://golang.org/pkg/go/build/#hdr-Build_Constraints)).
|
||
|
||
### Blockbook integration tests

|
||
### Back-end RPC integration tests
|
||
|
||
This kind of tests test *bchain.BlockChain* implementation and its capability to communicate with back-end RPC. Tests
|
||
of most of coins are similar so there is single generalized implementation in package *blockbook/bchain/tests/rpc*. Test
|
||
functions of particular coin implementation can just initialize test object and call its methods. Configuration of tests
|
||
is stored in *blockbook/bchain/tests/rpc/config.json* and consists of back-end URL and credentials. Every test suite also
|
||
has fixtures stored in *blockbook/bchain/tests/rpc/testdata*. Content is obvious from existing files.
|
||
|
||
For example see [bitcoinrpc_test.go](/bchain/coins/btc/bitcoinrpc_test.go).
