truffle/Assert.sol and DeployedAddresses.sol files are missing for me also. I am following Truffle's metacoin example steps, at what stage these files should have been created. I noticed when test command showed 0 passing message. Didn't receive any error message till this point.

truffle(develop)> truffle test
Using network 'develop'.
0 passing (0ms)

@KurtLorey @malaravannm This issue has also been raised in #756. In that instance, the poster re-installed their project and the issue self-resolved. They were also on Windows using VS Code. If someone discovers why this is happening or if the steps suggested don't work please feel free to re-open or comment here.

Closing as duplicate of #756.

reinstalling project doesn't work.

[chainchaser]

same here... not working on windows 10 environment.

VS Code,
Windows10,
truffle 4.1.11
node 8.11.2
npm 5.6.2

is there any way to solve it?

[lhbfahd]

what is mean by reinstalling the project ?
i deleted the project that i am working on ( pet-shop tutorial ) and cloned ( pet-shop-box ) and nothing changed.
and where should the global Truffle files be ?

It seems that this issue is related to naming conflict in Win env.
Try moving/renaming truffle.js in project root dir to truffle-config.js. This works for me.

Try to install truffle with -g option...

From the windos command line (i.e. the gitbash command line) it didn't work for me (Windows 7). But it worked from the truffle develop command line
truffle develop
truffle(develop)> test
or
truffle(develop)> test ./test/TestMetacoin.sol
truffle(develop)> test ./test/metacoin.js

From the windos command line (i.e. the gitbash command line) it didn't work for me (Windows 7). But it worked from the truffle develop command line
truffle develop
truffle(develop)> test
or
truffle(develop)> test ./test/TestMetacoin.sol
truffle(develop)> test ./test/metacoin.js

Thanks it worked over truffle(develop)>

I am working through the Pet Shop tutorial and was having the same issue. Truffle's "magic" files that aren't anywhere in your repository were causing errors to show up in my tests, although the tests still ran and passed fine.

Try to install truffle with -g option...

Doing this with npm install truffle -g and restarting VS Code fixed the issue. Thanks @sebastiankozub

[ericnickus]

Its not a windows issue I don't think. It's happening on my imac with BigSur
Truffle v5.4.14 (core: 5.4.14)
Solidity v0.5.16 (solc-js)
Node v16.6.2
Web3.js v1.5.3

[ndrslmpk]

Same issue here on Windows 10.
Truffle v5.4.5 (core: 5.4.5)
Solidity - ^0.8.0 (solc-js)
Node v16.6.1
Web3.js v1.5.1

Isn't there a way to locally download the truffle folders?

[cds-amal]

@ndrslmpk Can you open a new issue please? This will help us track and investigate the problem more efficiently. Thanks you!

[DigiCris]

Also happening on my ubuntu and I can't find a way to fix it.

[cds-amal]

Hi @DigiCris, can you open a new issue for this, please? What version of truffle are you using, and, if possible, do you have a repo you can share? thanks!
