## Testing Applications

Dash Core provides testing tools designed to let developers
|
|
test their applications with reduced risks and limitations.
|
|
|
|
{% endautocrossref %}
|
|
|
|
### Testnet
|
|
{% include helpers/subhead-links.md %}
|
|
|
|
{% autocrossref %}
|
|
|
|
When run with no arguments, all Dash Core programs default to Dash's main
|
|
network ([mainnet][/en/glossary/mainnet]{:#term-mainnet}{:.term}). However, for development,
|
|
it's safer and cheaper to use Dash's test network (testnet)
|
|
where the duffs spent have no real-world value. Testnet also relaxes some
|
|
restrictions (such as standard transaction checks) so you can test functions
|
|
which might currently be disabled by default on mainnet.
|
|
|
|
To use testnet, use the argument `-testnet`<!--noref--> with `dash-cli`, `dashd`
|
|
or `dash-qt` or add `testnet=1`<!--noref--> to your `dash.conf` file as
|
|
[described earlier][dashd initial setup]. To get free duffs for testing,
|
|
check the faucets listed below. They are community supported and due to
|
|
potentially frequent Testnet changes, one or more of them may be unavailable at
|
|
a given time:
|
|
|
|
* [Testnet Faucet - Dash.org]
|
|
* [Testnet Faucet - Masternode.io]
|
|
* [Testnet Faucet - Dashninja.pl]
|
|
|
|
Testnet is a public resource provided for free by members of the community,
|
|
so please don't abuse it.

### Regtest Mode
|
|
{% include helpers/subhead-links.md %}
|
|
|
|
{% autocrossref %}
|
|
|
|
For situations where interaction with random peers and blocks is unnecessary or
|
|
unwanted, Dash Core's regression test mode (regtest mode) lets you
|
|
instantly create a brand-new private block chain with the same basic
|
|
rules as testnet---but one major difference: you choose when to create
|
|
new blocks, so you have complete control over the environment.
|
|
|
|
Many developers consider regtest mode the preferred way to develop new
|
|
applications. The following example will let you create a regtest
|
|
environment after you first [configure dashd][dashd initial setup].
|
|
|
|
{% endautocrossref %}
|
|
|
|
{% highlight bash %}
|
|
> dashd -regtest -daemon
|
|
Dash Core server starting
|
|
{% endhighlight %}
|
|
|
|
{% autocrossref %}
|
|
|
|
Start `dashd` in regtest mode to create a private block chain.
|
|
|
|
{% endautocrossref %}
|
|
|

|
|
## Dash Core
|
|
dash-cli -regtest generate 101
|
|
~~~
|
|
|
|
{% autocrossref %}
|
|
|
|
Generate 101 blocks using a special RPC
|
|
which is only available in regtest mode. This takes less than a second on
|
|
a generic PC. Because this is a new block chain using Dash's default
|
|
rules, the first blocks pay a block reward of 500 dash. Unlike
|
|
mainnet, in regtest mode only the first 150 blocks pay a reward of 500 dash.
|
|
However, a block must have 100 confirmations before that reward can be
|
|
spent, so we generate 101 blocks to get access to the coinbase
|
|
transaction from block #1.
|
|
|
|
{% endautocrossref %}
|
|
|
|
{% highlight bash %}
|
|
dash-cli -regtest getbalance
|
|
500.00000000
|
|
{% endhighlight %}
|
|
|
|
{% autocrossref %}
|
|
|
|
Verify that we now have 500 dash available to spend.
|
|
|
|
You can now use Dash Core RPCs prefixed with `dash-cli -regtest`<!--noref-->.
|
|
|
|
Regtest wallets and block chain state (chainstate) are saved in the `regtest`<!--noref-->
|
|
subdirectory of the Dash Core configuration directory. You can safely
|
|
delete the `regtest`<!--noref--> subdirectory and restart Dash Core to
|
|
start a new regtest. (See the [Developer Examples Introduction][devexamples] for default
|
|
configuration directory locations on various operating systems. Always back up
|
|
mainnet wallets before performing dangerous operations such as deleting.)
