do you have dependencies between your tests? Do you use tearDown to clean your resources?

TestRunner anomaly

by Larry White

When I run my tests in TestRunner by clicking Run Selected, they all pass. When I run them by clicking Run Coverage, a couple fail. Does anyone know why that might be? thanks.

I just read http://www.ietf.org/rfc/rfc3207.txt It turns out that before doing the TLS negociation (connect handshake), some prior conversation is needed, including the STARTTLS command. I think this might be doable, I will try. Sven

Hi Sven, When I said 'hanging' i wasn't implying that mail didn't work: it can't connect to that server without SSL. Anyway, I tried to interrupt with CMD "." - I wasn't aware of that option - but now I'm getting the error msg back so fast I can't interrupt it. Sigh. I'll keep trying when I'm not on my day job.

Re: [Pharo-users] Status of SSL on Pharo? (and some general questions on mail and IO)

Larry, This works for me using our own SMTP server without the SSL option. Note that we have a custom port and of course don't allow annonymous relaying. | client | client := SMTPClient new. text := String streamContents: [ :stream | stream << 'Subject: Test'; crlf; crlf. stream << 'Hi there!'; crlf; << 'Sent from Pharo Smalltalk'; crlf ]. [ client user: 'sven(a)beta9.be'; password: '???'. client openOnHost: (NetNameResolver addressForName: 'smtp.beta9.be') port: 2525. client mailFrom: 'sven(a)beta9.be' to: #('svc(a)mac.com') text: text. client quit ] ensure: [ client close ]. client If you have Seaside in your image, look at the references of SMTPClient, they do something similar. Next, I will subclass SMTPClient to try to do an SSL connection with our server. Concerning the 'hanging': are you sure you cannot interrupt and enter the debugger using CMD-. ? What version of Pharo are you using and on which platform ?

This is what I ran (excepting the actual email addresses). [SMTP client deliverMailFrom: 'foo(a)gmail.com' to: #('bar(a)gmail.com') text: 'Subject: this is a test Hello from Pharo! ' usingServer: 'smtp.gmail.com' ] fork. it fails of course (no ssl) but it hangs while it tries. thanks.
