How to use go mod replace to test samples for new PR

1. Modify the seata-go dependency version to v0.0.0-incompatible, and remove the version number if it exists in the original dependency path.

   //github.com/seata/seata-go v1.0.3
   github.com/seata/seata-go v0.0.0-incompatibl
   

2. Find the absolute or relative path to your local code.

   /Users/mac/Desktop/GO/seata-go
   ../seata-go
   

3. Add the replace module to the go.mod file and change it to the local code path.

   github.com/seata/seata-go =>  ../seata-go
   

4. Synchronization dependencies.

   go mod tidy
   

5. Run the sample test code.

How to use go workspace to test samples for new PR (Recommended)

You can use your local project forked to test new pr that haven't merged into github.com/seata/seata-go.

1. Make sure your go version is 1.18 or later.

2. Fork and download two projects (seata-go and seata-go-samples), and put them into a same local directory.

For examples:

/Users/xxx/code/github.com/yourid/seata-go
/Users/xxx/code/github.com/yourid/seata-go-samples

1. Execute go work init command in projects root directory.

cd /Users/xxx/code/github.com/yourid

go work init

You will find a go.work file in /Users/xxx/code/github.com/yourid.

1. Add seata-go and seata-go-samples into the same go workspace.

go work use ./seata-go

go work use ./seata-go-samples

Now, the content of go.work file is as follows.

go 1.19

use (
        ./seata-go
        ./seata-go-samples
)

1. Run the sample test code in seata-go-samples.
